b7aa589217 Fix the build for MSVC 9 whose upper_bound() wants to compare elements in the sorted array.

d3c7e834e8 Fix some latent bugs if the nodes are unschedulable. We'd gotten away 
with this before since none of the register tracking or nightly tests
had unschedulable nodes.

This should probably be refixed with a special default Node that just
returns some "don't touch me" values.

Fixes PR9427

3faa2722ef Revert "Make a comparator's argument `const'. This fixes the build for 
MSVC 9."

The "fix" was meaningless.

This reverts commit r127245.

72d7cc25f3 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.

fd853e8757 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.
