2c5f19db2e 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.

f713384be5 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).

86e05af491 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.

cbf8a98c7c 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

26c5663283 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.
