UBSan: Don't diagnose inf/nan conversions between floating-point types. It's far from clear whether these have undefined behavior, and these checks are helping no-one. Keep the double->float overflow warnings, though, since those are useful in practice, even though it's unclear whether such operations have defined behavior.

Don't reject __restrict applied to a dependent type; it might instantiate to a pointer or reference type.

[Parser] Don't code-complete twice.

When we are consuming the current token just to enter a new token stream, we push
the current token in the back of the stream so that we get it again.

Unfortunately this had the effect where if the current token is a code-completion one,
we would code-complete once during consuming it and another time after the stream ended.

Fix this by making sure that, in this case, ConsumeAnyToken() will consume a code-completion
token without invoking code-completion.

Fold together the two implementations of 6.7.3p2 in SemaType. Fix two bugs, each of which was only present in one version:
 * Give the right diagnostic for 'restrict' applied to a non-pointer, non-reference type.
 * Don't reject 'restrict' applied indirectly to an Objective-C object pointer type (eg, through template instantiation).

Support C11 _Atomic type qualifier. This is more-or-less just syntactic sugar for the _Atomic type specifier.

Revert "Update debug info test for schema change made to LLVM."

This reverts commit 5035c483b7fcbf0fa2a7afba24fa35a10995d195.

This schema change wasn't necessary after all. I'm going ith a different
solution that will hopefully use space more conservatively.

For -Wignored-qualifiers, don't warn on qualifiers which we acquire via a

Add support for gcc-compatible -mmfcrf -mno-mfcrf PPC options

gcc provides -mmfcrf and -mno-mfcrf for controlling what we call
the mfocrf target feature. Also, PPC is now making use of the
static function AddTargetFeature used by the Mips Driver code.
