to modernity. Instead of passing down individual
context objects from parser to sema, establish decl
context in parser and have sema access current context
as needed. I still need to take of Doug's comment for
minor cleanups.

has already been loaded before allocating a new Module structure. If
the module has already been loaded (uniquing based on file name), then
just return the existing module rather than trying to load it again.

This allows us to load a DAG of modules. Introduce a simple test case
that forms a diamond-shaped module graph, and illustrates that a
source file importing the bottom of the diamond can see declarations
in all four of the modules that make up the diamond.

Note that this version moves the file-opening logic into the module
manager, rather than splitting it between the module manager and the
AST reader. More importantly, it properly handles the
weird-but-possibly-useful case of loading an AST file from "-".

Fix a memory leak in the analyzer - BugReports didn't get freed. Plus, remove invalid assert from the destructor which wasn't called previously due to the leak.

Enhance -Wstrl-incorrect-size to not report a FIXIT for destinations that are flexible arrays or have size 1.

One API change: I added BugReporter as an additional parameter to the BugReporterVisitor::VisitNode() method to allow visitors register other visitors with the report on the fly (while processing a node). This functionality is used by NilReceiverVisitor, which registers TrackNullOrUndefValue when the receiver is null.

Reapply r137903, but fix the definition of size_t in the test case to use __SIZE_TYPE__ (and hence be portable).

Also, change the warning to -Wstrl-incorrect-size.

Teach ModuleManager::addModule() to check whether a particular module
has already been loaded before allocating a new Module structure. If
the module has already been loaded (uniquing based on file name), then
just return the existing module rather than trying to load it again.

function declaration. The body may simply have not yet been attached.
This fixes PR10666.

There may be an alternate, preferred implementation strategy, see my
FIXME. Review would definitely be appreciated Doug. =D

-import-module) vs. loaded because some other module depends on
them. As part of doing this, pass down the module that caused a module
to be loaded directly, rather than assuming that we're loading a
chain. Finally, write out all of the directly-loaded modules when
serializing an AST file (using the new IMPORTS record), so that an AST
file can depend on more than one other AST file, all of which will be
loaded when that AST file is loaded. This allows us to form and load a
tree of modules, but we can't yet load a DAG of modules.

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)."

Currently this includes -pedantic warnings as well; we'll need to consider whether these should
be included.

This works as expected with -Werror.

Test cases were added to Sema/warn-unused-parameters.c, but they should probably be broken off into
their own test file.

Remove EnhancedBugReport and RangedBugReport - pull all the extra functionality they provided into their parent BugReport. The only functional changes are: made getRanges() non const - it adds default range to Ranges if none are supplied, made getStmt() private, which was another FIXME.
