definitions. We were rejecting tentative definitions of incomplete
(which is bad), and now we don't.
This fix is partial because we don't do the end-of-translation-unit
initialization for tentative definitions that don't ever have any
initializers specified.

the untimed version of getOrCreateSourceID. getOrCreateSourceID calls
GetOrCreateSourceID, of course.
- Move some methods into the "private" section. Constify at least one method.
- General clean-ups.

context of a template-id for which we need to instantiate default
template arguments.
In the TextDiagnosticPrinter, don't suppress the caret diagnostic if
we are producing a non-note diagnostic that follows a note diagnostic
with the same location, because notes are (conceptually) a part of the
warning or error that comes before them.

only print the template instantiation backtrace for the first error.
Also, if a base class has failed to type-check during instantiation,
just drop that base class and continue on to check other base classes.

'struct A<double, int>'
In the "template instantiation depth exceeded" message, print
"-ftemplate-depth-N" rather than "-ftemplate-depth=N".
An unnamed tag type that is declared with a typedef, e.g.,
typedef struct { int x, y; } Point;
can be used as a template argument. Allow this, and check that we get
sensible pretty-printing for such things.

scheduled in multiple regions, liveness data used by the
anti-dependence breaker is carried from one region to the next, however
the information reflects the state of the instructions before scheduling.
After scheduling, there may be new live range overlaps. Handle this by
pessimizing the liveness data carried between regions to the point where
it will be conservatively correct now matter how the earlier region is
scheduled. This fixes a miscompilation in 176.gcc with the post-RA
scheduler enabled.

to a diagnostic that will be invoked after the diagnostic (if it is
not suppressed). The hooks are allowed to produce additional
diagnostics (typically notes) that provide more information. We should
be able to use this to help diagnostic clients link notes back to the
diagnostic they clarify. Comments welcome; I'll write up documentation
and convert other clients (e.g., overload resolution failures) if
there are no screams of protest.
As the first client of post-diagnostic hooks, we now produce a
template instantiation backtrace when a failure occurs during template
instantiation. There's still more work to do to make this output
pretty, if that's even possible.

to obtain debug info about them.
Introduce helpers to access debug info for global variables. Also introduce a
helper that works for both local and global variables.

done in sema, and is reflected by the existing PR3258. In the meantime,
fix PR3682 by disabling a bogus assertion (which doesn't account for +

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.
