[ObjCARC Debug Message] - Added debug message when fuse a retain/autorelease pair in ObjCARCContract::ContractAutorelease.

[ObjCARC Debug Message] - Added debug message when we zap a matching retain/autorelease pair in ObjCARCOpt::OptimizeReturns.

llvm-svn: 171678

[ObjCARC Debug Message] - Added debug message when we erase ARC calls with null since they are no-ops.

llvm-svn: 171677

[ObjCARC Debug Message] - Added debug message when we add a nounwind keyword to a function which can not throw.

llvm-svn: 171676

[ObjCARC Debug Message] - Added debug message when we add a tail keyword to a function which can never be passed stack args.

Added debug statement to ObjCARC when we replace objc_autorelease(x) with objc_release(x) when x is otherwise unused.

llvm-svn: 171673

Added 2x Debug statements to ObjCARC that log when we handle the two undefined pointer-to-weak-pointer is NULL cases by replacing the given call inst with an undefined value.

The reason that there are two cases is that the first case handles the unary cases and the second the binary cases.

Added debug message in ObjCARC when we remove a no-op cast which has only special semantic meaning in the frontend and thus in the optimizer can be deleted.

llvm-svn: 171670

Added debug message to ObjCARC when we transform an objc_autoreleaseReturnValue => objc_autorelease due to its operand not being used as a return value.

Fix suffix handling for parsing and printing of cvtsi2ss, cvtsi2sd, cvtss2si, cvttss2si, cvtsd2si, and cvttsd2si to match gas behavior.

cvtsi2* should parse with an 'l' or 'q' suffix or no suffix at all. No suffix should be treated the same as 'l' suffix. Printing should always print a suffix. Previously we didn't parse or print an 'l' suffix.
cvtt*2si/cvt*2si should parse with an 'l' or 'q' suffix or not suffix at all. No suffix should use the destination register size to choose encoding. Printing should not print a suffix.

Original 'l' suffix issue with cvtsi2* pointed out by Michael Kuperstein.

these ideas don't get lost

If we find an unexpected closing brace, we must not stop parsing, as
we'd otherwise not layout anything beyond that point.

If we find a structural error on the highest level we'll not re-indent
anyway, but we'll still want to format within unwrapped lines.

Needed to introduce a differentiation between an expected and unexpected
closing brace.

Fix for PR14739. It's not safe to fold a load into a call across a store. Thanks to Nick Lewycky for the initial patch.

To parse # correctly, we need to know whether it is the first token in a
line - we can deduct this either from the whitespace or seeing that the
token is the first in the file - we already calculate this information.
This patch moves the identification of the first token into the
getNextToken method and stores it inside the FormatToken, so the
UnwrappedLineParser can stay independent of the SourceManager.

Uses indent 0 for macros for now and resets the indent state to the
level prior to the preprocessor directive.

A preprocessor directive cannot be started while we're parsing one.

Catch some cases I'd missed in r171605 related to unnamed parameters of record
type. This resolves all remaining cases of PR14573 suppression in the GDB 7.5
test suite. Fix to the test suite to follow.

Added debug message to ObjCARC when we transform objc_retainAutorelasedReturnValue => objc_retain since the operand to said function is not a return value.

Added debug message for ObjCARC when we zap an objc_autoreleaseReturnValue/objc_retainAutoreleasedValue pair.
