Don't call llvm_start_multithreaded() during init.  As of LLVM
revision r211277, this function is essentially a no-op.

Document unroll and unroll_count directives.

Extend the documentation for "#pragma clang loop" hints to include the unroll
and unroll_count directives.

Fix PR20069: bad loop pragma arguments crash FE

This patch fixes a crash when handling malformed arguments to loop pragmas such
as: "#pragma clang loop vectorize(()".  Essentially any argument which is not an
identifier or constant resulted in a crash.  This patch also changes a couple of
the error messages which weren't quite correct.  New behavior with this patch vs
old behavior:

#pragma clang loop vectorize(1)
OLD: error: missing keyword; expected 'enable' or 'disable'
NEW: error: invalid argument; expected 'enable' or 'disable'

#pragma clang loop vectorize()
OLD: error: expected ')'
NEW: error: missing argument to loop pragma 'vectorize'

#pragma clang loop vectorize_width(bad)
OLD: error: missing value; expected a positive integer value
NEW: error: invalid argument; expected a positive integer value

#pragma clang loop vectorize(bad)
OLD: invalid keyword 'bad'; expected 'enable' or 'disable'
NEW: error: invalid argument; expected 'enable' or 'disable'

Frontend: Add a CC1 flag to dump module dependencies to a directory

This adds the -module-dependency-dir to clang -cc1, which specifies a
directory to copy all of a module's dependencies into in a form
suitable to be used as a VFS using -ivfsoverlay with the generated
vfs.yaml.

This is useful for crashdumps that involve modules, so that the module
dependencies will be intact when a crash report script is used to
reproduce a problem on another machine.

We currently encode the absolute path to the dump directory, due to
limitations in the VFS system. Until we can handle relative paths in
the VFS, users of the VFS map may need to run a simple search and
replace in the file.

test: Just check the VFS when testing module-dependency-dump

Checking the filesystem seems to be a bit unreliable. Limit the tests

Avoid invalidating successfully loaded module files

Successfully loaded module files may be referenced in other
ModuleManagers, so don't invalidate them. Two related things are fixed:

1) I thought the last module in the manager was always the one that
failed, but it isn't.  So check explicitly against the list of
vetted modules from ReadASTCore.

2) We now keep the file descriptor of pcm file open, which avoids the
possibility of having two different pcms for the same module loaded when
building in parallel with headers being modified during a build.

Frontend: Disentangle removePathTraversal from concatenating paths

This reimplements part of r211303 in a bit of a cleaner way. Doing so
allows us to use a proper absolute path when calling addFileMapping
rather than relying on a substring being one, which should fix the
tests on Windows.

Fix/Improve SourceRange of explicitly defaulted members

When adding the implicit compound statement (required for Codegen?), the
end location was previously overridden by the start location, probably
based on the assumptions:

* The location of the compound statement should be the member's location
* The compound statement if present is the last element of a FunctionDecl

This patch changes the location of the compound statement to the
member's end location.
