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.

539c40505b Make shl instruction mask its result to the correct bitsize. This is
sufficient to get llvm-test/SingleSource/UnitTests/Integer/general-test.ll
working with lli in interpreter mode.

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.

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
its own version for each writer type.

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.

3af776359d Fix PR1114 and CodeGen/Generic/2007-01-15-LoadSelectCycle.ll by being
careful when folding "c ? load p : load q" that C doesn't reach either load.
If so, folding this into load (c ? p : q) will induce a cycle in the graph.

cfdd717db5 Fix for PR1095:
LLVM would miscompile ASM dialects when compiling for PPC. Added dialects for
the X86 and PPC backends. It defaults to "0", the first variant of a compound
inline asm expression.
