a8f4c1d137 __PPC64CompilationCallback code was allowing registers to be clobbered by stub.

5d79e6ff6c this is an initial patch to switch the ppc64 jit over to working in PIC mode, 
which allows the code to be above the 2G marker.  We still need to JIT emit
dyld stubs to support external, weak, common, etc globals, but that will
happen tomorrow.

2. Float values need to be promoted to double when they are vararg.

eb9b1840b3 on ppc64, float arguments take 8-byte stack slots not 4-byte stack slots. 
Also, valist should create a pointer RC reg class value, not a GPRC value.

f50d87eb50 Rewrite the branch selector to be correct in the face of large functions. 
The algorithm it used before wasn't 100% correct, we now use an iterative
expansion model.  This fixes assembler errors when compiling 403.gcc with
tail merging enabled.

Change the way the branch selector works overall: Now, the isel generates
PPC::BCC instructions (as it used to) directly, and these BCC instructions
are emitted to the output or jitted directly if branches don't need
expansion.  Only if branches need expansion are instructions rewritten
and created.  This should make branch select faster, and eliminates the
Bxx instructions from the .td file.

0d88b19f2f convert PPC::BCC to use the 'pred' operand instead of separate predicate 
value and CR reg #.  This requires swapping the order of these everywhere
that touches BCC and requires us to write custom matching logic for
PPCcondbranch :(

8aac7dc0ee This is a general clean up of the PowerPC ABI. Address several problems and 
bugs including making sure that the TOS links back to the previous frame,
that the maximum call frame size is not included twice when using frame
pointers, no longer growing the frame on calls, double storing of SP and
a cleaner/faster dynamic alloca.
