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.

ef9dd6b5db test/CodeGen/X86/vec_cast.ll: [PR8311] Add explicit -mtriple=x86_64-linux and -mtriple=x86_64-win32. Thanks to Nadav, it might be fixed in r126424.

a8389213a0 When decling to reuse existing expressions that involve casts, ignore 
bitcasts, which are really no-ops here. This fixes slowdowns on
MultiSource/Applications/aha and others.

b35d45a714 Target/X86: Always emit "push/pop GPRs" in prologue/epilogue and emit "spill/reload frames" for XMMs. 
It improves Win64's prologue/epilogue but it would not affect ia32 and amd64 (lack of nonvolatile XMMs).

412ffed4f0 Add some DAGCombines for (adde 0, 0, glue), which are useful to optimize legalized code for large integer arithmetic. 
1. Inform users of ADDEs with two 0 operands that it never sets carry
2. Fold other ADDs or ADDCs into the ADDE if possible

It would be neat if we could do the same thing for SETCC+ADD eventually, but we can't do that in target independent code.

ab7cf630f4 Enable support for vector sext and trunc: 
Limit the folding of any_ext and sext  into the load operation to scalars.
Limit the active-bits trunc optimization to scalars.
Document vector trunc and vector sext in LangRef.

Similar to commit 126080 (for enabling zext).

724eb8706a Merge information about the number of zero, one, and sign bits of live-out 
registers at phis. This enables us to eliminate a lot of pointless zexts during
the DAGCombine phase. This fixes <rdar://problem/8760114>.

It seems it affected configuration --target=i686-pc-mingw32, I don't know and will investigate why.
