dc95020e30 Added DAG xforms. e.g.
(vextract (v4f32 s2v (f32 load $addr)), 0) -> (f32 load $addr) 
(vextract (v4i32 bc (v4f32 s2v (f32 load $addr))), 0) -> (i32 load $addr)
Remove x86 specific patterns.

9b7ac95116 Next powerpc long double bits. Comparisons work,
although not well, and shortening FP converts.

2c4419d71b Generalize tcFullMultiply so that the operands can be of differing
part widths.  Also, return the number of parts actually required to
hold the result's value.
Remove an over-cautious condition from rounding of float->hex conversion.

2b3122e56e INC64_32r -> LEA64_32r is better than INC64_32r -> LEA32r, but it still can
cause performance degradation.

688f34a273 In 64-bit mode, avoid using leal with 32-bit 32-bit address size, e.g.
leal 1(%ecx), %edi, which requires 67H prefix.

c7b51b678d First round of ppc long double. call/return and
basic arithmetic works.
Rename RTLIB long double functions to distinguish
different flavors of long double; the lib functions
have different names, alas.

de07843bf3 If a node that defines a physical register that is expensive to copy. The
scheduler will try a number of tricks in order to avoid generating the
copies. This may not be possible in case the node produces a chain value
that prevent movement. Try unfolding the load from the node before to allow
it to be moved / cloned.

f536e2f41e - Added a few target hooks to generate load / store instructions from / to any
address (not just from / to frameindexes).
- Added target hooks to unfold load / store instructions / SDNodes into separate
load, data processing, store instructions / SDNodes.
