This backs out changes in commit r198605 and part of r198604, replacing the
original tok::kw_template with a slightly more obvious placeholder
tok::unknown.

It controls everything that -flimit-debug-info used to, plus the
vtable type optimization. The old -fno-limit-debug-info option is now an
alias to -fstandalone-debug and vice versa.
Standalone is the default on Darwin until dtrace is updated to work with
non-standalone debug info (rdar://problem/15758808).
Note: I kept the LimitedDebugInfo name in CodeGenOptions::DebugInfoKind
because NoStandaloneDebugInfo sounded even more confusing.

This matches up the underlying type against the actual storage type 'unsigned
short' and lets us get rid of some casts while we're at it.
Effort is made to keep this building in pre-C++11 but as with other features
Token will be less efficiently packed in in legacy configurations.
llvm-svn: 198607
Implemented with a new getKeywordSpelling() accessor. Unlike getTokenName() the
result of this function is stable and may be used in diagnostic output.
Uses of this feature are split out into the subsequent commit.

enum-scoped.cpp:93:6: error: enumeration redeclared with different underlying type 'short' (was 'int')
enum Redeclare6 : short;
^
enum-scoped.cpp:92:6: note: previous declaration is here
enum Redeclare6 : int;
^ ~~~
The redeclaration source range is still missing but this is a step forward,
potentially edging towards a FixIt.

This has the dual effect of (1) enabling more dead-stripping in release builds
and (2) ensuring that debug helper functions aren't stripped away in debug
builds, as they're intended to be called from the debugger.
Note that the attribute is applied to definitions rather than declarations in
headers going forward because it's now conditional on NDEBUG:
/// \brief Mark debug helper function definitions like dump() that should not be
/// stripped from debug builds.
Requires corresponding macro added in LLVM r198456.

Summary:
This makes us more compatible with MSVC 2012+ and fixes PR17748 where we
would give two tables the same name.
Rather than doing a fresh depth-first traversal of the inheritance graph
for every record's vbtables, now we memoize vbtable paths for each
record. By doing memoization, we end up considering virtual bases of
subobjects that come later in the depth-first traversal. Where
previously we would have ignored a virtual base that we'd already seen,
we now consider it for name mangling purposes without emitting a
duplicate vbtable for it.

- Remove the additions to ObjCMethodDecl & ObjCIVarDecl that were getting de/serialized and consolidate
all functionality for the checking for this warning in Sema::DiagnoseUnusedBackingIvarInAccessor
- Don't check immediately after the method body is finished, check when the @implementation is finished.
This is so we can see if the ivar was referenced by any other method, even if the method was defined after the accessor.
- Don't silence the warning if any method is called from the accessor silence it if the accessor delegates to another method via self.

Summary:
This allows for a better alternative to the FrontendAction hack used in
clang-tidy in order to get static analyzer's ASTConsumer.

Summary:
No functionality change.
This code should live here long-term because we should be able to use it
to compute correct vftable names.
It turns out that the most natural way to implement the naming algorithm
is to use a caching layer similar to what we already have for virtual
table info in VTableContext. Subsequent changes will take advantage of
this to fix PR17748, where we have a vbtable name collision.

The backend string is only verified when available as it's possible to run
clang IRGen for targets that haven't been built or don't exist in LLVM.

Remove UnaryTypeTraitExpr and switch all remaining type trait related handling
over to TypeTraitExpr.
The UTT/BTT/TT enum prefix and evaluation code is retained pending further
cleanup.
This is part of the ongoing work to unify type traits following the removal of
BinaryTypeTraitExpr in r197273.

1) Teach ExpectAndConsume() to emit expected and expected-after diagnostics
using the generic diagnostic descriptions added in r197972, eliminating another
set of trivial err_expected_* variations while maintaining existing behaviour.
2) Lift SkipUntil() recovery out of ExpectAndConsume(). The Expect/Consume
family of functions are primitive parser operations that now have the
well-defined property of operating on single tokens. Factoring out recovery
exposes opportunities for more consistent and tailored error recover at the
call sites instead of just relying on a bottled SkipUntil formula.
llvm-svn: 198270
Previously any error in enum definition body stopped parsing it. With this
change parser tries to recover from errors.
The patch fixes PR10982.
