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.

80bf052680 Provide an isPowerOf2ByteWidth method for the IntegerType class. This will 
mostly be used by back ends that wish to distinguish between integer types
that fit evenly within a natural integer type and those that don't.

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.

770735e1ca Modify emission of jump tables on darwin to emit an extra "l" label that 
delimits the boundaries of jump tables.  This lets the linker's dead code
stripping optimization do a better job.

1f1443b916 For PR1028: 
Add the llvm.stacksave and llvm.stackrestore intrinsics that correspond
to the GCC builtins __builtin_stack_save and __builtin_stack_restore. This
allows the CBE to execute these builtins, and fixes:

   test/CodeGen/CBackend/2007-01-17-StackSaveNRestore.ll
   External/SPEC/CINT2000/176.gcc (CBE)

33f1e701c9 For PR739: 
Support overriding the prefix and DESTDIR variables from the make command
line. This makes the makefile system a little more GNU compliant and the
feature makes it easier for distribution builders to re-target the install
location of LLVM.

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.

5789edd7f5 New "TargetObjInfo" class. This holds information that the object writers will 
use to write things to the file. It's abstract so each target should implement
