419f232783 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).

7466678003 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.

278be783b5 Revert "SimplifyCFG: GEPs with just one non-constant index are also cheap." 
Yes, there are other types than i8* and GEPs on them can produce an add+multiply.
We don't consider that cheap enough to be speculatively executed.

027f98cd3b test/lit.cfg: Add PATHEXT to 'substitution', to recognize tools on Windows hosts. Thanks to Danil Malyshev! 
Some tests on Windows use the "not" utility and fail with an error "program not executable". The reason for this error is that the name of the executable file sended to the "not" without the extension.

091b1e3c74 change instcombine to not turn a call to non-varargs bitcast of 
function prototype into a call to a varargs prototype.  We do
allow the xform if we have a definition, but otherwise we don't
want to risk that we're changing the abi in a subtle way.  On
X86-64, for example, varargs require passing stuff in %al.

33b7bebca4 Revert r125595, which is an X86-only undocumented assembly syntax extension 
enabled for all targets. Non-X86 targets should not have this behavior
enabled by default.

Joerg, if you would like to resubmit with the behavior conditionalized to be
X86-ELF only, that's fine.

e573fb3255 More fcopysign correctness and performance fix. 
The previous codegen for the slow path (when values are in VFP / NEON
registers) was incorrect if the source is NaN.

The new codegen uses NEON vbsl instruction to copy the sign bit. e.g.
        vmov.i32        d1, #0x80000000
        vbsl    d1, d2, d0
If NEON is not available, it uses integer instructions to copy the sign bit.
