Support fuzzy parsing MS line-oriented __asm's that originate from a macro (a case where we can't obtain source line info). As the test case indicates, we don't currently support line-oriented asm statements that mix file/macro body tokens.

improve error recovery handling broken 'then' or 'else' stmts in

Fix a parser bug on labeled inline asm stmts, allowing us
...
to parse stuff like:
asm volatile("1: rex64/fxrstor (%[fx])\n\t"
"2:\n"
".section .fixup,\"ax\"\n"
"3: movl $-1,%[err]\n"
" jmp 2b\n"
".previous\n"
".section __ex_table,\"a\"\n"
" .align 8\n"
" .quad 1b,3b\n"
".previous"
: [err] "=r" (err)
: [fx] "cdaSDb" (fx), "m" (*fx), "0" (0));

Break the assumption that any sort of scope (e.g. a loop scope) can

hold declarations. Instead, introduce a new "DeclScope" scope type that
holds them explicitly. For now, all scopes have this bit, but in the

In code like this:

Finally bite the bullet and make the major change: split the clang namespace
...
out of the llvm namespace. This makes the clang namespace be a sibling of
llvm instead of being a child.
The good thing about this is that it makes many things unambiguous. The
bad things is that many things in the llvm namespace (notably data structures
like smallvector) now require an llvm:: qualifier. IMO, libsystem and libsupport
should be split out of llvm into their own namespace in the future, which will fix
this issue.

When parsing an expr in stmt context, make sure to consume the semicolon
...
after the expr along with the expr. If we don't do this, the semicolon
gets parsed as a nullstmt, which makes the generated AST very strange.
