Evgeniy Stepanov 5dfe9f2b2f Extend unwind.h with the ARM unwinder interface.
These declarations come from the sample code in the
"Exception Handling ABI for the ARM Architecture" document.

Evgeniy Stepanov 84c44a8b8b EHABI-based stack trace on ARM.
The change removes the unused FLAG_fast_unwind, and forces EHABI-based unwind
on ARM, and fast (FP-based) unwind everywhere else.

Greg Clayton e42ae8497f Fixed an issue with the Instruction subclasses where the strings might
be fetched too many times and the DisassemblerLLVM was appending to strings
when the opcode, mnemonic and comment accessors were called multiple times
and if any of the strings were empty.

Also fixed the test suite failures from recent Objective C modifications.

Sean Callanan a9bc065607 Fixed a problem where maintaining the ObjCInterfaceMap
for each ObjCInterfaceDecl was imposing performance
penalties for Objective-C apps.  Instead, we now use
the normal function query mechanisms, which use the
relevant accelerator tables.

This fix also includes some modifications to the
SymbolFile which allow us to find Objective-C methods
and report their Clang Decls correctly.

Evan Cheng 2879467d4e - Slight change to finalizeBundle() interface. LastMI is not exclusive (pointing
to instruction right after the last instruction in the bundle.
- Add a finalizeBundle() variant that doesn't specify LastMI. Instead, the code
  will find the last instruction in the bundle by following the 'InsideBundle'
  marker. This is useful in case bundles are formed early (i.e. during MI
  scheduling) but finalized later (i.e. after register allocator has finished
  rewriting virtual registers with physical registers).

Richard Smith f8379a0fc3 constexpr: converted constant expression handling for enumerator values, case
values and non-type template arguments of integral and enumeration types.

This change causes some legal C++98 code to no longer compile in C++11 mode, by
enforcing the C++11 rule that narrowing integral conversions are not permitted
in the final implicit conversion sequence for the above cases.

Jakob Stoklund Olesen ff482f733b Add experimental -x86-use-regmask command line option.

Jakob Stoklund Olesen f1fb1d2375 Ignore register mask operands when lowering instructions to MC.
This is similar to implicit register operands.  MC doesn't understand
register liveness and call clobbers.

Jakob Stoklund Olesen 9349351d72 Add a RegisterMaskSDNode class.
This SelectionDAG node will be attached to call nodes by LowerCall(),
and eventually becomes a MO_RegisterMask MachineOperand on the
MachineInstr representing the call instruction.

LowerCall() will attach a register mask that depends on the calling
convention.

Jim Grosbach d4dbd09d85 MCAssembler tweak for determining when a symbol difference is resolved.
If the two fragments are in the same Atom, then the difference
expression is resolvable at compile time. Previously we were checking
that they were in the same fragment, but that breaks down in the
presence of instruction relaxation which has multiple fragments in the
same atom.

Kaelyn Uhrain b1378408e4 Convert SemaDecl.cpp to pass callback objects to CorrectTypo.
Includes tests highlighting the cases where accuracy has improved
(there is one call that does no filtering beyond selecting the set
of allowed keywords, and one call that only triggers for ObjC code
for which a test by someone who knows ObjC would be welcome). Also
fixes a small typo in one of the suggestion messages, and drops a
malformed "expected-note" for a suggestion that did not occur even
when the malformed note was committed as r145930.

Douglas Gregor 4fc9f3e819 Optimize unqualified/global name lookup in modules by introducing a
generational scheme for identifiers that avoids searching the hash
tables of a given module more than once for a given
identifier. Previously, loading any new module invalidated all of the
previous lookup results for all identifiers, causing us to perform the
lookups repeatedly.
