19f7969f81 1) Improve comments. 
2) Don't try to insert an i64 value into the low part of a 
   vector with movq on an x86-32 target.  This allows us to 
   compile:

__m128i doload64(short x) {return _mm_set_epi16(0,0,0,0,0,0,0,1);}

into:

_doload64:
	movaps	LCPI1_0, %xmm0
	ret

instead of:

_doload64:
	subl	$28, %esp
	movl	$0, 4(%esp)
	movl	$1, (%esp)
	movq	(%esp), %xmm0
	addl	$28, %esp
	ret

5f5bf3a3fd PPC64 passes arguments of integral type in i64 registers, not i32. Reflect this 
by promoting smaller integral values (i32 at this point) to i64, then truncating
to get the wanted size.

ad2715e0d7 - Fix support for "special" i64 immediates that can be loaded 
using IL, ILA, et. al. v2i64 and i64 are now supported by
  the select bits (SELB) instruction.

- Add missing comparison operations (testcase forthcoming)

- More multiclass refactoring.

6fd599fa69 Add a target lowering hook to control whether it's worthwhile to compress fp constant. 
For x86, if sse2 is available, it's not a good idea since cvtss2sd is slower than a movsd load and it prevents load folding. On x87, it's important to shrink fp constant since fldt is very expensive.

7194aaf738 This is the initial check-in for adding register scavenging to PPC. (Currently, 
PPC-64 doesn't work.) This also lowers the spilling of the CR registers so that
it uses a register other than the default R0 register (the scavenger scrounges
for one). A significant part of this patch fixes how kill information is
handled.
