- 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).

Keep track of whether a class is abstract or not. This is currently only used for the __is_abstract type trait.

a name with setName that does not make a temporary std::string.

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>).

 - PR3854.

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.
