This looks like it had a small, but measurable performance improvement on -O0
compile time for our ObjC tests.

Make sure a variable with a C++ direct initializer triggers jump scope checking.  Fixes PR10620 / <rdar://problem/9958362> .

enable us to track the depth of parsing and what is being parsed. This
helps when trying to track down difficult type parsing issues and is only
enabled in non-production builds.

It was never updated for API changes in r149311/r149336/r149339

Hardcoding the location of the build directory seems like it would
break at `make install`/packaging time.

Double fields of by-value class objects should be passed in floating point
registers.

Kill the brief and full explanation fields from StaticDiagInfoRec. They were unused and wasted space for nothing.

Unify default construction of error_code uses on this idiom so that users don't
feel compelled to make static globals for naming convenience. (unfortunately I
couldn't make the original ctor private as some APIs don't return their result,
instead using an out parameter (that makes sense to default construct) - which
is a bit of a pity. I did, however, find/fix some cases of unnecessary default
construction of error_code before I hit the unfixable cases)

class objects follow the same rules as those returning struct objects.

Also fix a logic error for a missing return stmt. Oops.

This only adds the interference checks required for correctness.
We still need to take advantage of register masks for the
interference driven live range splitting.

GlobalOpt runs early in the pipeline (before inlining) and complex class
hierarchies often introduce bitcasts or GEPs which weren't optimized away.
Teach it to ignore side-effect free instructions instead of depending on
other passes to remove them.

Teach the MC and disassembler about SoftFail, and hook it up to UNPREDICTABLE on ARM. Wire this to tBLX in order to provide test coverage.

core isue 975, which allows multiple return statements so long as the
types match. ExtWarn when user code is actually making use of this
