Don't emit calls to virtual [[noreturn]] functions as noreturn; overrides of a
[[noreturn]] function are not required to also be [[noreturn]]. We still emit
calls to virtual __attribute__((noreturn)) functions as noreturn; unlike GCC,
we do require overriders to also be noreturn for that attribute.

Mips specific inline assembler constraint 'R'

'R' An address that can be sued in a non-macro load or store.

Including missing positive test case and fixed typo for r176453.

Thanks to Richard Smith for catching this!

Use ASTContext::getDeclAlign(<Field Decl>) to get the alignment of the first
field to be memcpy'd, rather instead of ASTContext::getTypeAlign(<Field Type>).
For packed structs the alignment of a field may be less than the alignment of
the field's type.

Preprocessor: don't consider // to be a line comment in -E -std=c89 mode.

It's beneficial when compiling to treat // as the start of a line
comment even in -std=c89 mode, since it's not valid C code (with a few
rare exceptions) and is usually intended as such. We emit a pedantic
warning and then continue on as if line comments were enabled.
This has been our behavior for quite some time.

However, people use the preprocessor for things besides C source files.
In today's prompting example, the input contains (unquoted) URLs, which
contain // but should still be preserved.

This change instructs the lexer to treat // as a plain token if Clang is
in C90 mode and generating preprocessed output rather than actually compiling.

Preprocessor: don't keep comments under -traditional-cpp.

This patch is designed for minimal intrusion into normal preprocessing
and compilation; under -E -traditional-cpp, the lexer will still
generate tok::comment nodes since it is preserving all whitespace, but
the output printer will then throw it away.

continue parsing the directive rather than silently discarding it.

Allowing undef or redef of __TIME__ and __DATE__ is important to folks
