- 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.

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>).

 - 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.
