Alter the ExternalASTSource interface to permit by-name lookups. PCH continues to

bring in the entire lookup table at once.
Also, give ExternalSemaSource's vtable a home. This is important because otherwise
any reference to it will cause RTTI to be emitted, and since clang is compiled
with -fno-rtti, that RTTI will contain unresolved references (to ExternalASTSource's
RTTI). So this change makes it possible to subclass ExternalSemaSource from projects
compiled with RTTI, as long as the subclass's home is compiled with -fno-rtti.

If a function definition has any sort of weak linkage, its static local

variables should have internal linkage. To avoid computing this excessively,
set a function's linkage before we emit code for it.

fixes that and also gives better linkage than 'weak' when merging is required.

IRgen/C++: When mark vtables used, make sure to still append to the VTableUse array if we promote a vtable from being just used to having its definition required.

These restrictions are intended to keep VLAs out of the parts of the
C++ type system where they cause the most trouble. Fixes PR5678 and

Improve our handling of reference binding for subobjects of
...
temporaries. There are actually several interrelated fixes here:
- When converting an object to a base class, it's only an lvalue
cast when the original object was an lvalue and we aren't casting
pointer-to-derived to pointer-to-base. Previously, we were
misclassifying derived-to-base casts of class rvalues as lvalues,
causing various oddities (including problems with reference binding
not extending the lifetimes of some temporaries).
- Teach the code for emitting a reference binding how to look
through no-op casts and parentheses directly, since
Expr::IgnoreParenNoOpCasts is just plain wrong for this. Also, make
sure that we properly look through multiple levels of indirection
from the temporary object, but destroy the actual temporary object;
this fixes the reference-binding issue mentioned above.
- Teach Objective-C message sends to bind the result as a temporary
when needed. This is actually John's change, but it triggered the
reference-binding problem above, so it's included here. Now John
can actually test his return-slot improvements.

'-fasm' and explicitly map from that flag to -fgnu-keywords in the driver. Turn

Driver: When printing a "command was signalled" type of diagnostic, use the
...
short name of the tool in use, instead of the name of the action that created
the command. The practical impact is we now get:
clang: error: clang frontend command failed due to signal 6 (use -v to see invocation)
instead of:
clang: error: assembler command failed due to signal 6 (use -v to see invocation)
when clang crashes on a job that uses the integrated assembler.

Improve recovery when we see a dependent template name that is missing
...
the required "template" keyword, using the same heuristics we do for
dependent template names in member access expressions, e.g.,
test/SemaTemplate/dependent-template-recover.cpp:11:8: error: use 'template'
keyword to treat 'getAs' as a dependent template name
T::getAs<U>();
^
template

Improve parser recovery when we encounter a dependent template name
...
that is missing the 'template' keyword, e.g.,
t->getAs<T>()
where getAs is a member of an unknown specialization. C++ requires
that we treat "getAs" as a value, but that would fail to parse since T
is the name of a type. We would then fail at the '>', since a type
cannot be followed by a '>'.
This is a very common error for C++ programmers to make, especially
since GCC occasionally allows it when it shouldn't (as does Visual
C++). So, when we are in this case, we use tentative parsing to see if
the tokens starting at "<" can only be parsed as a template argument
list. If so, we produce a diagnostic with a fix-it that states that
the 'template' keyword is needed:
test/SemaTemplate/dependent-template-recover.cpp:5:8: error: 'template' keyword
is required to treat 'getAs' as a dependent template name
t->getAs<T>();
^
template
This is just a start of this patch; I'd like to apply the same
approach to everywhere that a template-id with dependent template name
can be parsed.
