- Make the Diagnostic::Level for PTH errors to be specified by the caller
clang (driver):
- Set the PTHManager diagnostic level to "Diagnostic::Error" for -include-pth
(a hard error) and Diagnostic::Warning for -token-cache (we can still
proceed).

in release-assert builds. For automatic variables, explicitly set
a name with setName that does not make a temporary std::string.
This speeds up -emit-llvm-only -disable-free on PR3810 by 4.6%

lists. The code wasn't accounting for the distinction between the
top-level call to getStructuredSubobjectInit and later calls that
occur deeper in the hierarchy. This problem manifested itself as
over-allocation in cases where we have large arrays of small
structures (<rdar://problem/6707362>).

I think it makes more sense to change MemoryBuffer::getSTDIN (return 0
should indicate error, not empty), but it is documented to return 0
for empty inputs, and some other code appears to rely on this.

1. it wasn't applying to definitions, only declarations, e.g. int x __asm("foo")
2. multiple definitions were conflicting, they weren't getting merged.
3. the code was duplicated in several places.

unneeded bitcast is requested. This is common for frontends who just unconditionally
cast even if the target is often the right type already. THis prevents going into
getFoldedCast which switches on the opcode and does a bunch of other stuff before
doing the same opzn.

This speeds up getAsIdentifierInfo from being a call to a function
with a big switch to a single testl instruction. This speeds up
the example in PR3810 by 6.2%

its vectors based on the subobject type we're initializing and the
(unstructured) initializer list. This eliminates some malloc thrashing
when parsing initializers (from 117 vector reallocations down to 0
when parsing Cocoa.h). We can't always pre-allocate the right amount
of storage, since designated initializers can cause us to initialize
in non-predictable patterns.

- <rdar://problem/6669441> ccc doesn't handle assembler-with-cpp
semantics correctly (but clang supports it)
- This is sad, because it requires a fairly useless target
hook. C'est la vie.
