4e4294bdee Added a new format for displaying an array of characters: eFormatCharArray
This us useful because sometomes you have to show a single character as: 'a'
(using eFormatChar) and other times you might have an array of single 
charcters for display as: 'a' 'b' 'c', and other times you might want to 
show the contents of buffer of characters that can contain non printable
chars: "\0\x22\n123". 

This also fixes an issue that currently happens when you have a single character
C string (const char *a = "a"; or char b[1] = { 'b' };) that was being output
as "'a'" incorrectly due to the way the eFormatChar format output worked.

f3ef3d2af9 Added new lldb_private::Process memory read/write functions to stop a bunch
of duplicated code from appearing all over LLDB:

lldb::addr_t
Process::ReadPointerFromMemory (lldb::addr_t vm_addr, Error &error);

bool
Process::WritePointerToMemory (lldb::addr_t vm_addr, lldb::addr_t ptr_value, Error &error);

size_t
Process::ReadScalarIntegerFromMemory (lldb::addr_t addr, uint32_t byte_size, bool is_signed, Scalar &scalar, Error &error);

size_t
Process::WriteScalarToMemory (lldb::addr_t vm_addr, const Scalar &scalar, uint32_t size, Error &error);

in lldb_private::Process the following functions were renamed:

From:
uint64_t
Process::ReadUnsignedInteger (lldb::addr_t load_addr, 
                              size_t byte_size,
                              Error &error);

To:
uint64_t
Process::ReadUnsignedIntegerFromMemory (lldb::addr_t load_addr, 
                                        size_t byte_size,
                                        uint64_t fail_value, 
                                        Error &error);

Cleaned up a lot of code that was manually doing what the above functions do
to use the functions listed above.

Added the ability to get a scalar value as a buffer that can be written down
to a process (byte swapping the Scalar value if needed):

uint32_t 
Scalar::GetAsMemoryData (void *dst,
                        uint32_t dst_len, 
                        lldb::ByteOrder dst_byte_order,
                        Error &error) const;

The "dst_len" can be smaller that the size of the scalar and the least 
significant bytes will be written. "dst_len" can also be larger and the
most significant bytes will be padded with zeroes. 

Centralized the code that adds or removes address bits for callable and opcode
addresses into lldb_private::Target:

lldb::addr_t
Target::GetCallableLoadAddress (lldb::addr_t load_addr, AddressClass addr_class) const;

lldb::addr_t
Target::GetOpcodeLoadAddress (lldb::addr_t load_addr, AddressClass addr_class) const;

All necessary lldb_private::Address functions now use the target versions so
changes should only need to happen in one place if anything needs updating.

Fixed up a lot of places that were calling :

addr_t
Address::GetLoadAddress(Target*);

to call the Address::GetCallableLoadAddress() or Address::GetOpcodeLoadAddress()
as needed. There were many places in the breakpoint code where things could
go wrong for ARM if these weren't used.

7349bd9078 While implementing unwind information using UnwindAssemblyInstEmulation I ran
into some cleanup I have been wanting to do when reading/writing registers.
Previously all RegisterContext subclasses would need to implement:

virtual bool
ReadRegisterBytes (uint32_t reg, DataExtractor &data);

virtual bool
WriteRegisterBytes (uint32_t reg, DataExtractor &data, uint32_t data_offset = 0);

There is now a new class specifically designed to hold register values: 
        lldb_private::RegisterValue
        
The new register context calls that subclasses must implement are:

virtual bool
ReadRegister (const RegisterInfo *reg_info, RegisterValue &reg_value) = 0;

virtual bool
WriteRegister (const RegisterInfo *reg_info, const RegisterValue &reg_value) = 0;

The RegisterValue class must be big enough to handle any register value. The
class contains an enumeration for the value type, and then a union for the 
data value. Any integer/float values are stored directly in an appropriate
host integer/float. Anything bigger is stored in a byte buffer that has a length
and byte order. The RegisterValue class also knows how to copy register value
bytes into in a buffer with a specified byte order which can be used to write
the register value down into memory, and this does the right thing when not
all bytes from the register values are needed (getting a uint8 from a uint32
register value..). 

All RegiterContext and other sources have been switched over to using the new
regiter value class.

dc4e9637ac Added the ability to get an set the desired format for SBValue objects.
Fixed the display of complex numbers in lldb_private::DataExtractor::Dump(...)
and also fixed other edge display cases in lldb_private::ClangASTType::DumpTypeValue(...).

1d3afba3a3 Added a new ValueObject type that will be used to freeze dry expression
results. The clang opaque type for the expression result will be added to the
Target's ASTContext, and the bytes will be stored in a DataBuffer inside
the new object. The class is named: ValueObjectConstResult

Now after an expression is evaluated, we can get a ValueObjectSP back that
contains a ValueObjectConstResult object.

Relocated the value object dumping code into a static function within
the ValueObject class instead of being in the CommandObjectFrame.cpp file
which is what contained the code to dump variables ("frame variables").

ed8a705cea General command line help cleanup:
- All single character options will now be printed together
- Changed all options that contains underscores to contain '-' instead
- Made the help come out a little flatter by showing the long and short
  option on the same line.
- Modified the short character for "--ignore-count" options to "-i"

d88d759a74 15-20% speed improvement when parsing DWARF. I used instruments to
find the hotspots in our code when indexing the DWARF. A combination of
using SmallVector to avoid collection allocations, using fixed form
sizes when possible, and optimizing the hot loops contributed to the
speedup.

enabled LLVM make style building and made this compile LLDB on Mac OS X. We
