900cc96e08 Implement skeletal support for __.SYMDEF (ranlib) sections in archives. 
Correctly parse the Long Filename section of the archive.
When reading in archive members, set their ModuleIDs to
 "ARCHIVENAME(MEMBERNAME)", as is traditional.

93dea78f85 I can't believe the incompetence of the people I have to deal with around here. 
These fools don't even wrap code at 80 columns.

Oh wait, _I_ wrote that.  That explains a lot!!

cd45bc4086 Fix PR 110: the constant folding code assumes that if something is not a 
constant expression, but is of (for example) ubyte type, then it is a
ConstantUInt.  This was not true for placeholders.

2d05c60bac Add support for 'weak' linkage. 
For now, we translate linkonce into weak linkage in the bytecode format because
we don't have enough bits to represent it.  We will rev the bytecode version
soon anyways, so this will be fixed in the near future.

fdf472a83a Ok, the "fix" for this is to do a real associative container. Symbol tables 
are ordered by name, not by slot, so the previous solution wasn't any good.
On a large testcase, this reduces time to parse from 2.17s to 1.58s.

e7691a4520 Major refactoring of the bytecode reader. This includes the following 
changes:
  * BytecodeReader::getType(...) used to return a null pointer
    on error.  This was only checked about half the time.  Now we convert
    it to throw an exception, and delete the half that checked for error.
    This was checked in before, but psmith crashed and lost the change :(
  * insertValue no longer returns -1 on error, so callers don't need to
    check for it.
  * Substantial rewrite of InstructionReader.cpp, to use more efficient,
    simpler, data structures.  This provides another 5% speedup.  This also
    makes the code much easier to read and understand.

bd26abdc95 Significantly clean up parsing of instructions. This exceptionizes and 
simplifies the control flow a bit.  This provides a small (~3%) speedup,
but it's primarily a cleanup exercise.

42dce1e365 Eliminate the old LateResolveValues data structure, replacing it with a 
new, simpler, ForwardReferences data structure.  This is just the first
simple replacement, subsequent changes will improve the code more.

This simple change improves the performance of loading a file from HDF5
(contributed by Bill) from 2.36s to 1.93s, a 22% improvement.  This
presumably has to do with the fact that we only create ONE placeholder for
a particular forward referenced values, and also may be because the data
structure is much simpler.

abf6412c09 This patch substantially simplifies and cleans up handling of basic blocks 
in the bytecode parser.  Before we tried to shoehorn basic blocks into the
"getValue" code path with other types of values.  For a variety of reasons
this was a bad idea, so this patch separates it out into its own data structure.

This simplifies the code, makes it fit in 80 columns, and is also much faster.
In a testcase provided by Bill, which has lots of PHI nodes, this patch speeds
up bytecode parsing from taking 6.9s to taking 2.32s.  More speedups to
follow later.
