7c2cdb1c05 Turn on list-ilp scheduling by default on x86 and x86-64, fix up 
testcases accordingly. Some are currently xfailed and will be filed
as bugs to be fixed or understood.

Performance results:

roughly neutral on SPEC
some micro benchmarks in the llvm suite are up between 100 and 150%, only
a pair of regressions that are due to be investigated

john-the-ripper saw:
10% improvement in traditional DES
8% improvement in BSDI DES
59% improvement in FreeBSD MD5
67% improvement in OpenBSD Blowfish
14% improvement in LM DES

Small compile time impact.

0bf56c821c Further improvements to pre-RA-sched=list-ilp. 
This change uses the MaxReorderWindow for both height and depth, which
tends to limit the negative effects of high register pressure.
