lib/Support/CrashRecoveryContext.cpp: Add Win32 support to CrashRecoveryContext. Thanks to Aaron Ballman!

lib/Support/Windows/Windows.h: Require at least Windows XP(5.1) API. We will not support Windows 2000 any more.

This pleases the register scavenger and brings
test/CodeGen/ARM/2011-08-12-vmovqqqq-pseudo.ll a little closer to
working with -verify-machineinstrs.

llvm-svn: 138164

Therefore, rather then generate a pseudo instruction, which is later expanded,
generate the necessary instructions in place.

then don't split it a second time, since that block will be dead.

Do not use named md nodes to track variables that are completely optimized. This does not scale while doing LTO with debug info. New approach is to include list of variables in the subprogram info directly.

The irony is not lost that this is not a completely trivial patchset.

the intent seems to be to terminate even in Release builds, just use abort()
directly.

If program flow ever reaches a __builtin_unreachable (which llvm_unreachable is
#define'd to on newer GCCs) then the program is undefined.
