destroy objects, release objects, etc. Fixes <rdar://problem/10531073>.

whether an expression is a (core) constant expression as a side-effect of
evaluation. This takes us from accepting far too few expressions as ICEs to
accepting slightly too many -- fixes for the remaining cases are coming next.
The diagnostics produced when an expression is found to be non-constant are
currently quite poor (with generic wording but reasonable source locations),
and will be improved in subsequent commits.

they are treated as errors.
Doing typo correction when these are just warnings slows down the
compilation of source which deliberately uses implicit function
declarations.

in addition to underlying type.
For example, the warning for printf("%zu", 42.0);
changes from "conversion specifies type 'unsigned long'" to "conversion
specifies type 'size_t' (aka 'unsigned long')"
(This is a second attempt after r145697, which got reverted.)

of void type, to ensure that we can still fold ((void)0, 1) as an array bound.

void foo() {}

}
Only applies to non-weak functions, and does not apply if the function address
is taken explicitly with the addr-of operator.

Basically typo correction will try to offer a correction instead of looking into type dependent base classes.
I found this problem while parsing Microsoft ATL code with clang.

within module maps, which will (eventually) be used to re-export a
module from another module. There are still some pieces missing,
however.
llvm-svn: 145665
(sub)module, all of the names may be hidden, just the macro names may
be exposed (for example, after the preprocessor has seen the import of
the module but the parser has not), or all of the names may be
exposed. Importing a module makes its names, and the names in any of
its non-explicit submodules, visible to name lookup (transitively).
This commit only introduces the notion of name visible and marks
modules and submodules as visible when they are imported. The actual
name-hiding logic in the AST reader will follow (along with test cases).

force the unknown any type to "id" so that the message send can be
completed without requiring a case. Fixes <rdar://problem/10506646>.

Along the way, refactor some other code which similarly cares about whether or
not they are looking at a template instantiation.

serialization::Module to serialization::ModuleFile to side-step the
annoying naming conflict. Prune a bunch of ModuleMap.h includes that
are no longer needed (most files only needed the Module type).

really bad way to go about this, but I'm not sure there's a better
choice without substantial changes to TreeTransform --- most
notably, preserving implicit semantic nodes instead of discarding
and rebuilding them.
