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.

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.

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

Refactor and fix checking for initialization of flexible array members.  The old version had the checks scattered across the code, missed some checks, and had a couple nasty bugs in existing checks.

Fixes PR10648 and another similar accepts-invalid bug.

system flags an error when unlocking a lock which was not held, locking
the same lock twice, having a different lockset on each iteration of a
loop, or going out of scope while still holding a lock. In order to
successfully use the lockset, this patch also makes sure that attribute
arguments are attached correctly for later parsing.

This patch was also worked on by DeLesley Hutchins.

Note: This patch has been reviewed by Chandler Carruth and Jeffrey
Yasskin. Feel free to provide post-commit review comments for a
subsequent patch.

For the test case added to function-redecl.cpp, we were previously complaining

There may be an alternate, preferred implementation strategy, see my

Revert r137903, "Add experimental -Wstrlcpy-size warning that looks to see if the size argument for strlcpy/strlcat is the size of the *source*, and not the size of the *destination*.  This warning is off by default (for now)."
