asm. This allows us to properly handle the case when an optimizer duplicates
the asm, such as here:
void bar() {
int i;
for (i = 0; i < 3; ++i)
asm("foo %=" : : "r"(0));
}
we now produce:
_bar:
xorl %eax, %eax
## InlineAsm Start
foo 0
## InlineAsm End
## InlineAsm Start
foo 1
## InlineAsm End
## InlineAsm Start
foo 2
## InlineAsm End
ret
instead of:
_bar:
xorl %eax, %eax
## InlineAsm Start
foo 1
## InlineAsm End
## InlineAsm Start
foo 1
## InlineAsm End
## InlineAsm Start
foo 1
## InlineAsm End
ret
This also fixes a fixme by eliminating a static.

- Group control flow and event PathDiagnosticPieces into PathDiagnosticMacroPieces.
- Afterwards, eliminate any PathDiagnosticMacroPieces from a PathDiagnostic that
contain no informative events.
HTMLDiagnostics:
- Use new information about PathDiagnosticMacroPieces to specially format
message bubbles for macro expansions containing interesting events.

(default: 99). Beyond this limit, produce an error and consider the
current template instantiation a failure.
The stack we're building to track the instantiations will, eventually,
be used to produce instantiation backtraces from diagnostics within
template instantiation. However, we're not quite there yet.
This adds a new Clang driver option -ftemplate-depth=NNN, which should
eventually be generated from the GCC command-line operation
-ftemplate-depth-NNN (note the '-' rather than the '='!). I did not
make the driver changes to do this mapping.

such as replacing 'T' in vector<T>. There are a few aspects to this:
- Extend TemplateArgument to allow arbitrary expressions (an
Expr*), and switch ClassTemplateSpecializationType to store
TemplateArguments rather than it's own type-or-expression
representation.
- ClassTemplateSpecializationType can now store dependent types. In
that case, the canonical type is another
ClassTemplateSpecializationType (with default template arguments
expanded) rather than a declaration (we don't build Decls for
dependent types).
- Split ActOnClassTemplateId into ActOnClassTemplateId (called from
the parser) and CheckClassTemplateId (called from
ActOnClassTemplateId and InstantiateType). They're smart enough to
handle dependent types, now.

a warning and then threw away the AST. While I'm in there, tighten up the
code to actually reject completely bogus cases (sending a message to a
struct). We still allow sending a message to an int, which doesn't make
sense but GCC allows it and is easy to support.

Redefinition checking should ignore the leading whitespace and
start of line flags on the first token of an expansion.

Obj-C metadata variables (which generally should be handled the same,
although they aren't currently).
- No functionality change.

This prevents caret diagnostics from the scratch buffer from
including other tokens in the scratch buffer that occurred beforei
them.

end of line instead of just the end of buffer. Scratch buffers contain
embedded \0's between tokens which are logic line separators. If a
normal text buffer contains \0's, it doesn't make a lot of sense to include
them in the caret diag output anyway.

suggested by Eli.

This is a bit cleaner, and also "fixes" bad code that compares the
addresses of the string constants.
