support both a fragile and non-fragile ABI, and it can be selected at
runtime.  That driver option also works on Darwin (although obviously
the code is not necessarily usable if the system runtime is fragile)
so just do that.

Special case disassembler handling of REX.B prefix on NOP instruction to decode as XCHG R8D, EAX instead. Fixes PR10344.

otherwise these tests would fail on hosts that happen to default
to that, since that affects whether default synthesis can happen.

Fix another major performance regression in LiveVariables by not canonicalizing the underlying ImmutableSets on every analyzed statement (just at merges).  Fixes <rdar://problem/10087538>.

increasingly prevailing case to the point that new features
like ARC don't even support the fragile ABI anymore.

This required a little bit of reshuffling with exceptions
because a check was assuming that ObjCNonFragileABI was
only being set in ObjC mode, and that's actually a bit
obnoxious to do.

Most, though, it involved a perl script to translate a ton
of test cases.

Mostly no functionality change for driver users, although
there are corner cases with disabling language-specific
exceptions that we should handle more correctly now.

Fix LiveVariables analysis bug with MaterializeTemporaryExpr and fix handling in ExprEngine.  Fixes <rdar://problem/10201666>.

Fix disassembler handling of CRC32 which is an odd instruction that uses 0xf2 as an opcode extension and allows the opsize prefix. This necessitated adding IC_XD_OPSIZE and IC_64BIT_XD_OPSIZE contexts. Unfortunately, this increases the size of the disassembler tables. Fixes PR10702.

Moved type construction out of the loop and added an assert on the legality of the type. Formatted lines to the 80 char limit.

Make the suffixes optional everywhere, and just make sure they have the
right value. The suffixes aren't the interesting part of this test
anyways.

Sorry for the churn as I let the bots try out various patterns.

part on patches by Peter Collingbourne.

We diverge from the C++11 standard in a few areas, mostly related to checking
constexpr function declarations, and not just definitions. See WG21 paper
N3308=11-0078 for details.

Function invocation substitution is not available in this patch; constexpr
functions cannot yet be used from within constant expressions.
