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.

The old DenseMap hashed order was very confusing.

lambda expressions. Because these issue was pulled back from Ready
status at the Kona meeting, we still emit an ExtWarn when using
default arguments for lambda expressions.

template is defined, and then the specialization is referenced again, don't
forget to instantiate the template on the second reference. Use the source
location of the first reference as the point of instantiation, though.

* if, switch, range-based for: warn if semicolon is on the same line.
* for, while: warn if semicolon is on the same line and either next
statement is compound statement or next statement has more
indentation.

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

Tests from SemaCXX/if-empty-body.cpp merged into SemaCXX/warn-empty-body.cpp.

Remove the functionality of using 'frame variable -w' to set a watchpoint now that 'watchpoint set variable/expression'
is working.  Also update the relevant test cases.

(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.

Patch by Matt Johnson

llvm-svn: 150508

The MachO back-end needs to emit the garbage collection flags specified in the
module flags. This is a WIP, so the front-end hasn't been modified to emit these
flags just yet. Documentation and front-end switching to occur soon.
