No test because I can't think of any way to write one that won't break quickly.

Douglas Gregor 21673c4e7e Scoped enumerations should not be treated as integer types (in the C
sense). Fixes <rdar://problem/9366066> by eliminating an inconsistency
between C++ overloading (which handled scoped enumerations correctly)
and C binary operator type-checking (which didn't).

Douglas Gregor 1d33f8d8a0 With invalid overloaded operators, we can get into funny cases where
the overloading of member and non-member functions results in arity
mismatches that don't fit well into our overload-printing scheme. This
only happens for invalid code (which breaks the arity invariants for
these cases), so just suppress the diagnostic rather than inventing
anything new. Fixes <rdar://problem/9222009>.

Jakob Stoklund Olesen 1d3854d583 Disable physical register coalescing by default.
Joining physregs is inherently dangerous because it uses a heuristic to avoid
creating invalid code. Linear scan had an emergency spilling mechanism to deal
with those rare cases. The new greedy allocator does not.

The greedy register allocator is much better at taking hints, so this has almost
no impact on code size and quality. The few cases where it matters show up as
unit tests that now have -join-physregs enabled explicitly.

Jakob Stoklund Olesen 369bddf5ad Fix a batch of x86 tests to be coalescer independent.
Most of these tests require a single mov instruction that can come either before
or after a 2-addr instruction. -join-physregs changes the behavior, but the
results are equivalent.

Bill Wendling 2a40131f6b SjLj EH could produce a machine basic block that legitimately has more than one
landing pad as its successor.

SjLj exception handling jumps to the correct landing pad via a switch statement
that's generated right before code-gen. Loosen the constraint in the machine
instruction verifier to allow for this. Note, this isn't the most rigorous check
since we cannot determine where that switch statement came from. But it's
marginally better than turning this check off when SjLj exceptions are used.
