Owen Anderson c237a849e3 Re-apply r113679, which was reverted in r113720, which added a paid of new instcombine transforms 
to expose greater opportunities for store narrowing in codegen.  This patch fixes a potential
infinite loop in instcombine caused by one of the introduced transforms being overly aggressive.

Rafael Espindola 9fd2ed9243 Factoring and potential bug fix. The elf "flags" cannot be used as masks. 
For example, setting STT_OBJECT (1) and STT_FUNC (2), should not produce
a STT_SECTION (3).

Michael J. Spencer ff24bf78ea CMake: Fix MSVS build. Although I don't know why this didn't break other build systems... 
This problem is unrelated to the recent dependency tracking change. It
seems like noone noticed the problem because I don't think anyone compiles
any target other than X86 on windows.

Chris Lattner b47c042e09 add support for pushfd/popfd which are aliases for pushfl/popfl.

Chris Lattner a2a9d16b78 fix the asmparser so that the target is responsible for skipping to 
the end of the line on a parser error, allowing skipping to happen
for syntactic errors but not for semantic errors.  Before we would
miss emitting a diagnostic about the second line, because we skipped
it due to the semantic error on the first line:

  foo %eax
  bar %al

This fixes rdar://8414033 - llvm-mc ignores lines after an invalid instruction mnemonic errors

Owen Anderson 70f4524427 Invert and-of-or into or-of-and when doing so would allow us to clear bits of the and's mask. 
This can result in increased opportunities for store narrowing in code generation.  Update a number of
tests for this change.  This fixes <rdar://problem/8285027>.

Additionally, because this inverts the order of ors and ands, some patterns for optimizing or-of-and-of-or
no longer fire in instances where they did originally.  Add a simple transform which recaptures most of these
opportunities: if we have an or-of-constant-or and have failed to fold away the inner or, commute the order 
of the two ors, to give the non-constant or a chance for simplification instead.

Bill Wendling 041230014c Move some of the decision logic for converting an instruction into one that sets 
the 'zero' bit down into the back-end. There are other cases where this logic
isn't sufficient, so they should be handled separately.

Benjamin Kramer 8c35fb0739 Teach InstructionSimplify to fold (A & B) & A -> A & B and (A | B) | A -> A | B. 
Reassociate does this but it doesn't catch all cases (e.g. if the operands are i1).

Bill Wendling aee679bf35 Modify the comparison optimizations in the peephole optimizer to update the 
iterator when an optimization took place. This allows us to do more insane
things with the code than just remove an instruction or two.
