Andreas Neustifter 3d207290fe Cheap, mostly strict, stable sorting. 
This is necessary for tests so the results are comparable.

Evan Cheng 732351f732 Fix PR5391: support early clobber physical register def tied with a use (ewwww) 
- A valno should be set HasRedefByEC if there is an early clobber def in the middle of its live ranges. It should not be set if the def of the valno is defined by an early clobber.
- If a physical register def is tied to an use and it's an early clobber, it just means the HasRedefByEC is set since it's still one continuous live range.
- Add a couple of missing checks for HasRedefByEC in the coalescer. In general, it should not coalesce a vr with a physical register if the physical register has a early clobber def somewhere. This is overly conservative but that's the price for using such a nasty inline asm "feature".

Jakob Stoklund Olesen defc47088a Move PHIElimination::isLiveOut method to LiveVariables. 
We want LiveVariables clients to use methods rather than accessing the
getVarInfo data structure directly. That way it will be possible to change the
LiveVariables representation.

precisely, which prevents us from infinitely peeling the loop.

Jakob Stoklund Olesen 26667abbd3 Use CFG connectedness as a secondary sort key when deciding the order of copy coalescing. 
This means that well connected blocks are copy coalesced before the less connected blocks. Connected blocks are more difficult to
coalesce because intervals are more complicated, so handling them first gives a greater chance of success.

Oscar Fuentes 5c600b5435 Add two CMake flags LLVM_ENABLE_PEDANTIC and LLVM_ENABLE_WERROR, 
PEDANTIC defaults to ON and WERROR default to off.

Also add MSVC warnings. To disable warnings add the flags
LLVM_ENABLE_WARNINGS (default on).
