d16ce17711 Fixes a problem in instruction selection with testing whether or not the 
transformation:

(X op C1) ^ C2 --> (X op C1) & ~C2 iff (C1&C2) == C2

should be done.  

This change has been tested:

613dfb219c SlotIndexes used to store the index list in a crufty custom linked-list. I can't 
for the life of me remember why I wrote it this way, but I can't see any good
reason for it now. This patch replaces the custom linked list with an ilist.

This change should preserve the existing numberings exactly, so no generated code
should change (if it does, file a bug!).

689ff9c00f Implement GDB integration for source level debugging of code JITed using 
the MCJIT execution engine.

The GDB JIT debugging integration support works by registering a loaded
object image with a pre-defined function that GDB will monitor if GDB
is attached. GDB integration support is implemented for ELF only at this
time. This integration requires GDB version 7.0 or newer.

Patch by Andy Kaylor!

f1a60c734c Fix updateTerminator to be resiliant to degenerate terminators where 
both fallthrough and a conditional branch target the same successor.
Gracefully delete the conditional branch and introduce any unconditional
branch needed to reach the actual successor. This fixes memory
corruption in 2009-06-15-RegScavengerAssert.ll and possibly other tests.

Also, while I'm here fix a latent bug I spotted by inspection. I never
applied the same fundamental fix to this fallthrough successor finding
logic that I did to the logic used when there are no conditional
branches. As a consequence it would have selected landing pads had they
be aligned in just the right way here. I don't have a test case as
I spotted this by inspection, and the previous time I found this
required have of TableGen's source code to produce it. =/ I hate backend
bugs. ;]

Thanks to Jim Grosbach for helping me reason through this and reviewing
the fix.

1fbfea7b06 This patch fixes 3 problems: 
1. CHECKNEXT was used instead of CHECK-NEXT which caused the line to be
   ignored which in turn hid the next 2 problems:
2. ('sh_offset', 0x{{{[0-9,a-f]+}}) had one too many leading curly braces and
   failed to do it's job of accepting all hex digits and:
3. The check for the hex values for the code instructions didn't account for
   blank separators.

Patch by Jack Carter.
