f284b201e7 Preliminary support for inline asm in the cbe. The target specific ugliness 
is still in Writer, but issolated to a single function. This might be split
into something in each target directory.  This is sufficient to get through
archie and an strcpy impl on linux-x86.

Module level asm is not handled.

6010c0ef4a When truncating to bool, it is necessary to & with 1 for all casts that 
can result in a bool. Previously PtrToInt, FPToUI and FPToSI were missing
this operation.

992d9788b3 For PR950: 
The long awaited CAST patch. This introduces 12 new instructions into LLVM
to replace the cast instruction. Corresponding changes throughout LLVM are
provided. This passes llvm-test, llvm/test, and SPEC CPUINT2000 with the
exception of 175.vpr which fails only on a slight floating point output
difference.

86e39c84b6 Fix codegen for x86-64 on systems (like ppc or i386) that don't have 64-bit 
features autodetected.  This fixes PR1010 and Regression/CodeGen/X86/xmm-r64.ll
on non-x86-64 hosts.

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 :(

a9176b38f9 For unsigned 8-bit division. Use movzbw to set the lower 8 bits of AX while 
clearing the upper 8-bits instead of issuing two instructions. This also
eliminates the need to target the AH register which can be problematic on
x86-64.

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.

bd95b9d4ae Stop using isTwoAddress, switching to operand constraints instead. 
Tell the codegen emitter that specific operands are not to be encoded, fixing
JIT regressions w.r.t. pre-inc loads and stores (e.g. lwzu, which we generate
even when general preinc loads are not enabled).
