af3564823f For this transform: store V, (cast P) -> store (cast V), P 
don't allow the transform if V and the pointer's element type are different
width integer types.

14b42c0040 For PR1043: 
This is the final patch for this PR. It implements some minor cleanup
in the use of IntegerType, to wit:
1. Type::getIntegerTypeMask -> IntegerType::getBitMask
2. Type::Int*Ty changed to IntegerType* from Type*
3. ConstantInt::getType() returns IntegerType* now, not Type*

This also fixes PR1120.

Patch by Sheng Zhou.

ced4fcb608 Remove this xform: 
(shl (add x, c1), c2) -> (add (shl x, c2), c1<<c2)
Replace it with:
(add (shl (add x, c1), c2), ) -> (add (add (shl x, c2), c1<<c2), )

This fixes test/CodeGen/ARM/smul.ll

f6b1a88a1a - Target PIC style is no longer affected by relocation model. 
- In x86-64 mode, symbols with external linkage (not just symbols which are
  defined externally) requires GOT indirect reference.

7ba10cda74 Clean up some code around the store V, (cast P) -> store (cast V), P 
transform. Change some variable names so it is clear what is source and
what is dest of the cast. Also, add an assert to ensure that the integer
to integer case is asserting if the bitwidths are different. This prevents
illegal casts from being formed and catches bitwidth bugs sooner.

08e261a5f6 Fix a regression in the last patch. When constructing a BitMask, be careful 
not to overflow 64-bits and end up with a 0 mask. This caused i64 values to
always be stored as 0 with lots of consequential damage to nightly test.

0524da8d3d Two changes: 
1. Fix logic for executeGEP. Only 32-bit and 64-bit integer types are
   acceptable as indices.
2. Ensure that all integer cast operations truncate their result to the
   integer size of the operand.

2509765bef * Fix one more bug in PIC codegen: extra load is needed for *all* 
non-statics.
* Introduce new option to output zero-initialized data to .bss section.
This can reduce size of binaries. Enable it by default for ELF &
Cygwin/Mingw targets. Probably, Darwin should be also added.

9dc290a59b For PR1117: 
Make the assembler generate a nice error message if a bad cast instruction
is attempted instead of asserting out. This is made possible by the
recently exposed method CastInst::castIsValid() which checks the validity
of any cast instruction.
