2341c22ec7 Changes to support making the shift instructions be true BinaryOperators. 
This feature is needed in order to support shifts of more than 255 bits
on large integer types.  This changes the syntax for llvm assembly to
make shl, ashr and lshr instructions look like a binary operator:
   shl i32 %X, 1
instead of
   shl i32 %X, i8 1
Additionally, this should help a few passes perform additional optimizations.

d27f95e08d add initial support for handling inline asms with multiple constraints. 
This doesn't do the "right thing" but will probably work in most cases.

d7035b654b Use TargetData to obtain the correct size of the "size_t" argument for 
functions like memcpy, memmove and memset. Ensure only one prototype is
used for these functions and that it matches the system definition by
using the appropriate type for the size argument.

c7765617d2 For PR1138: 
Force memcpy to be the 32-bit variant. Since this is only used with
CBE and lli which both target 32-bit machines, this should be okay.

037c867b54 Propagate changes from my local tree. This patch includes: 
1. New parameter attribute called 'inreg'. It has meaning "place this
parameter in registers, if possible". This is some generalization of
gcc's regparm(n) attribute. It's currently used only in X86-32 backend.
2. Completely rewritten CC handling/lowering code inside X86 backend.
Merged stdcall + c CCs and fastcall + fast CC.
3. Dropped CSRET CC. We cannot add struct return variant for each
target-specific CC (e.g. stdcall + csretcc and so on).
4. Instead of CSRET CC introduced 'sret' parameter attribute. Setting in
on first attribute has meaning 'This is hidden pointer to structure
return. Handle it gently'.
5. Fixed small bug in llvm-extract + add new feature to
FunctionExtraction pass, which relinks all internal-linkaged callees
from deleted function to external linkage. This will allow further
linking everything together.

NOTEs: 1. Documentation will be updated soon.
       2. llvm-upgrade should be improved to translate csret => sret.
          Before this, there will be some unexpected test fails.
