Jakob Stoklund Olesen 8b9dce5c18 Don't attempt to use flags from predicated instructions. 
The ARM backend can eliminate cmp instructions by reusing flags from a
nearby sub instruction with similar arguments.

Don't do that if the sub is predicated - the flags are not written
unconditionally.

Michael Ilseman 0666f0580c Fold multiply by 0 or 1 when in UnsafeFPMath mode in SelectionDAG::getNode(). 
This folding happens as early as possible for performance reasons, and to make sure it isn't foiled by other transforms (e.g. forming FMAs).

Benjamin Kramer 8dd0edc7b1 c bindings: revert LLVMConstInlineAsm to always use the default asm dialect. 
- The C API should be stable
- InlineAsm::AsmDialect is not exposed to C
- The function didn't match the prototype so this was unreachable code

Benjamin Kramer 2b11eb0729 DSE: Poking holes into a SetVector is expensive, avoid it if possible. 
llvm-svn: 163480

Benjamin Kramer 851c941b8b LiveVariables: Compute a set of defs and kills to speed up updating LV during critical edge splitting. 
Previously we checked if the register is def'd in a block via the def/use list a
nd walked the list of kills to check if the register is killed in a block. Both
of these checks can be made much cheaper by walking the block first and
recording all defs and kills.

This reduces the compile time of the test case from PR13651 from 40s to 15s at
-O2. The compile time is still dominated by LV updating but now the main culprit
is SparseBitVector's slowness.

Benjamin Kramer 68b9f0583f Fix alignment of .comm and .lcomm on mingw32. 
For some reason .lcomm uses byte alignment and .comm log2 alignment so we can't
use the same setting for both. Fix this by reintroducing the LCOMM enum.
I verified this against mingw's gcc.

Jakob Stoklund Olesen e45e22b20f Custom DAGCombine for and/or/xor are for all ARMs.

Benjamin Kramer 47f9ec92cb MC: Overhaul handling of .lcomm 
- Darwin lied about not supporting .lcomm and turned it into zerofill in the
  asm parser. Push the zerofill-conversion down into macho-specific code.
- This makes the tri-state LCOMMType enum superfluous, there are no targets
  without .lcomm.
- Do proper error reporting when trying to use .lcomm with alignment on a target
  that doesn't support it.
- .comm and .lcomm alignment was parsed in bytes on COFF, should be power of 2.
- Fixes PR13755 (.lcomm crashes on ELF).

Benjamin Kramer e3d658bb6c PR13754: llvm-mc/x86 crashes on .cfi directives without the % prefix for registers. 
gas accepts this and it seems to be common enough to be worth supporting. This
doesn't affect the parsing of reg operands outside of .cfi directives.
