Jeffrey Yasskin 307c053f2e ExecutionEngine::clearGlobalMappingsFromModule failed to remove reverse
mappings, which could cause errors and assert-failures.  This patch fixes that,
adds a test, and refactors the global-mapping-removal code into a single place.

Dale Johannesen 96a5b87ae2 Use names instead of numbers for some of the magic
constants used in inlining heuristics (especially
those used in more than one file).  No functional change.

Kevin Enderby a2b99107c4 Added another bit of the ARM target assembler to llvm-mc to parse register
lists.  Changed ARMAsmParser::MatchRegisterName to return -1 instead of 0 on
errors so 0-15 values could be returned as register numbers.  Also added the
rest of the arm register names to the currently hacked up version to allow more
testing.  Some changes to ARMAsmParser::ParseOperand to give different errors
for things not yet supported and some additions to the hacked
ARMAsmParser::MatchInstruction to allow more testing for now.

Dan Gohman e19c1810d7 isTriviallyReMaterializable checks the
TargetInstrDesc::isRematerializable flag, so it isn't necessary to do
this check in its callers.

Dan Gohman 7d9dffb413 Fix the x86 test-shrink optimization so that it doesn't shrink comparisons
when one of the bits being tested would end up being the sign bit in the
narrower type, and a signed comparison is being performed, since this would
change the result of the signed comparison. This fixes PR5132.

Dale Johannesen 3059924bdd When considering whether to inline Callee into Caller,
and that will make Caller too big to inline, see if it
might be better to inline Caller into its callers instead.
This situation is described in PR 2973, although I haven't
tried the specific case in SPASS.
