loads the named module. The syntax itself is intentionally hideous and
will be replaced at some later point with something more
palatable. For now, we're focusing on the semantics:
- Module imports are handled first by the preprocessor (to get macro
definitions) and then the same tokens are also handled by the parser
(to get declarations). If both happen (as in normal compilation),
the second one is redundant, because we currently have no way to
hide macros or declarations when loading a module. Chris gets credit
for this mad-but-workable scheme.
- The Preprocessor now holds on to a reference to a module loader,
which is responsible for loading named modules. CompilerInstance is
the only important module loader: it now knows how to create and
wire up an AST reader on demand to actually perform the module load.
- We search for modules in the include path, using the module name
with the suffix ".pcm" (precompiled module) for the file name. This
is a temporary hack; we hope to improve the situation in the
future.

cases we want the prefix to be the original file name less the suffix. For an
input such as test.c to named temporary would be something like test-3O4Clq.o

after having already deserialized the fields, clear out the fields
first. This makes sure that we keep all of the declarations in the
lexical context (including those implicitly added by later
type-checking) within the same list. A test case for this behavior is
coming as part of another commit; testing for this problem in
isolation is a nightmare.

really shouldn't be optional. Fix the remaining place where a
temporary was being passed as potentially-aliased memory.

Also convert stack-addr-ps.cpp to use the analyzer instead of just Sema, now
that it doesn't crash, and extract the stack-block test into another file since
it errors, and that prevents the analyzer from running.

Much to everyone's surprise, the default constructor for TypeResult produces
an instance with Invalid == false. This seems like a decision we may want to
revisit.

emit call results into potentially aliased slots. This allows us
to properly mark indirect return slots as noalias, at the cost
of requiring an extra memcpy when assigning an aggregate call
result into a l-value. It also brings us into compliance with
the x86-64 ABI.

from the given source. -emit-module behaves similarly to -emit-pch,
except that Sema is somewhat more strict about the contents of
-emit-module. In the future, there are likely to be more interesting
differences.

to "when loading a particular module" validation, since it was only
validating local information anyway. This shouldn't change anything.
