JIT when printing the values of registers (e.g.,
"expr $pc").  Now the expression parser can do this
in the IR interpreter without running code in the
inferior process.

is general goodness because representations of member pointers are
not always equivalent across member pointer types on all ABIs
(even though this isn't really standard-endorsed).

Take advantage of the new information to teach IR-generation how
to do these reinterprets in constant initializers.  Make sure this
works when intermingled with hierarchy conversions (although
this is not part of our motivating use case).  Doing this in the
constant-evaluator would probably have been better, but that would
require a *lot* of extra structure in the representation of
constant member pointers:  you'd really have to track an arbitrary
chain of hierarchy conversions and reinterpretations in order to
get this right.  Ultimately, this seems less complex.  I also
wasn't quite sure how to extend the constant evaluator to handle
foldings that we don't actually want to treat as extended
constant expressions.

Pretend that regmask interference ends at the 'dead' slot, even when
there is other interference ending at the 'reg' slot of the same
instruction.

Perform all comparisons at instruction granularity, and make sure
register masks on uses count in both gaps.

llvm-svn: 150530

Only accept register masks when looking for an 'overlapping' def. When
Overlap is not set, the function searches for a proper definition of
Reg.

This means MI->modifiesRegister() considers register masks, but
MI->definesRegister() doesn't.

When a physreg is live in to a basic block, look for any instruction in
the block that clobbers the physreg.

The instruction doesn't have to properly redefine the register, any
overlapping clobber is OK.

This slightly changes live ranges when compiling with register masks.

Replacing the semicolon with {} or moving the semicolon to the next
line will always silence the warning.

(In response of Ted's review of r150112.)

This moves the logic which checked if a symbol escapes through a
parameter to invalidateRegionCallback (instead of post CallExpr visit.)

To accommodate the change, added a CallOrObjCMessage parameter to
checkRegionChanges callback.
