Code generation support for C99 designated initializers.
...
The approach I've taken in this patch is relatively straightforward,
although the code itself is non-trivial. Essentially, as we process
an initializer list we build up a fully-explicit representation of the
initializer list, where each of the subobject initializations occurs
in order. Designators serve to "fill in" subobject initializations in
a non-linear way. The fully-explicit representation makes initializer
lists (both with and without designators) easy to grok for codegen and
later semantic analyses. We keep the syntactic form of the initializer
list linked into the AST for those clients interested in exactly what
the user wrote.
Known limitations:
- Designating a member of a union that isn't the first member may
result in bogus initialization (we warn about this)
- GNU array-range designators are not supported (we warn about this)

Some micro-optimizations for DISABLE_SMART_POINTERS:
...
- When it's safe, ActionResult uses the low bit of the pointer for
the "invalid" flag rather than a separate "bool" value. This keeps
GCC from generating some truly awful code, for a > 3x speedup in the
result-passing microbenchmark.
- When DISABLE_SMART_POINTERS is defined, store an ActionResult
within ASTOwningResult rather than an ASTOwningPtr. Brings the
performance benefits of the above to smart pointers with
DISABLE_SMART_POINTERS defined.
Sadly, these micro-benchmark performance improvements don't seem to
make much of a difference on Cocoa.h right now. However, they're

a speedup for c99-intconst-1.c, speeding it up from 1.96s to 1.80s,

This change refactors some of the low-level lexer interfaces a bit.
...
Token now has a class of kinds for "literals", which include
numeric constants, strings, etc. These tokens can optionally have
a pointer to the start of the token in the lexer buffer. This
makes it faster to get spelling and do other gymnastics, because we
don't have to go through source locations.
This change is performance neutral, but will make other changes
more feasible down the road.

eagerly resolve the spelling locations of macro argument preexpansions.
...
This reduces fsyntax-only time on c99-intconst-1.c from 2.43s down to
2.01s (20%), reducing the number of fileid lookups from 2529040 linear
and 64771121 binary to 5625902 linear and 4151182 binary.
This knocks getFileID down to only 4.6% of compile time on this testcase.
At this point, malloc/free is over 35% of compile time, primarily allocating
MacroArgs objects and their argument preexpansion vectors.
I don't feel like malloc avoiding right now, so I'm just going to call
this good.

Eagerly resolve the spelling location of the tokens in a definition

of a macro. Since these tokens may themselves be from macro
expansions, we need to resolve down to the spelling loc when the
macro ends up being instantiated. Instead of resolving this for
each token expanded from the macro definition, just do it once when
the macro is defined. This speeds up clang on c99-intconst-1.c from
2.66s to 2.43s (9.5%), reducing the FileID lookups from 407244 linear and
114175649 binary to 2529040 linear and 64771121 binary.

This is a follow-up to r62675:
...
Refactor how the preprocessor changes a token from being an tok::identifier to a
keyword (e.g. tok::kw_for). Instead of doing this in HandleIdentifier, hoist this
common case out into the caller, so that every keyword doesn't have to go through
HandleIdentifier. This drops time in HandleIdentifier from 1.25ms to .62ms, and
speeds up clang -Eonly with PTH by about 1%.

Handle any undeclared parameters in a K&R-style function with a
...
special action, inside function prototype scope. This avoids confusion
when we try to inject these parameters into the scope of the function
body before the function itself has been added to the surrounding
scope. Fixes <rdar://problem/6097326>.

When getting the element region type, we should get the rvalue type of the super

region. Otherwise we would get an extra level of pointer type.
