1544f79e36 Fix nasty mingw32 bug, which e.g. prevented llvm-gcc bootstrap there. 
Mark _alloca call as clobberring EFLAGS, otherwise some DCE might remove
other flags-clobberring stuff (e.g. cmp instructions) occuring after
_alloca call.

a68e2a53a1 Revert invalid r111792. Jump tables are not broken on x86-64 / coff, 
it's COFF emitter which does not support differences of two symbols
(and needs to be fixed). GAS is pretty fine with code produced.

comparison is in a different basic block from the branch. In such
cases, the comparison's operands may not have initialized virtual

1998fbbf1a Prepare LowerVECTOR_SHUFFLEv8i16 to use x86 target specific nodes directly

Bruno Cardoso Lopes
28d9071635 This is the first step towards refactoring the x86 vector shuffle code. The 
general idea here is to have a group of x86 target specific nodes which are
going to be selected during lowering and then directly matched in isel.

The commit includes the addition of those specific nodes and a *bunch* of
patterns, and incrementally we're going to switch between them and what we
have right now. Both the patterns and target specific nodes can change as
we move forward with this work.
