This allows code indexing, etc. to use the VFS in the same way as the
compiler.

Sema does have a CUDALaunchBoundsAttr, but CodeGen was doing nothing with it.
This change translates CUDALaunchBoundsAttr to maxntidx and minctasm
metadata, which NVPTX then translates to the correct PTX directives.

This implements clause C.8 of the AAPCS in the front-end, so that Clang
accurately knows when the registers run out and it has to insert padding before
the stack objects begin.

Specifically, for a nested block or lambda, don't try to put the single
statement body inline, if it exceeds the column limit.

This should not change any observable behavior (as those would never
have led to the 'best' solution), but significantly speeds up formatting
time.

This fixes llvm.org/PR18761. Formatting time goes down from ~100s to a
few ms.

To differentiate between two modules with the same name, we will
consider the path the module map file that they are defined by* part of
the ‘key’ for looking up the precompiled module (pcm file).
Specifically, this patch renames the precompiled module (pcm) files from
  cache-path/<module hash>/Foo.pcm
to
  cache-path/<module hash>/Foo-<hash of module map path>.pcm

In addition, I’ve taught the ASTReader to re-resolve the names of
imported modules during module loading so that if the header search
context changes between when a module was originally built and when it
is loaded we can rebuild it if necessary.  For example, if module A
imports module B

first time:
clang -I /path/to/A -I /path/to/B ...

second time:
clang -I /path/to/A -I /different/path/to/B ...

will now rebuild A as expected.

* in the case of inferred modules, we use the module map file that
allowed the inference, not the __inferred_module.map file, since the
inferred file path is the same for every inferred module.

Currently the on disk hash table's key_iterator and data_iterator make
the assumption that the table data starts exactly four bytes after the
base of the table. This happens to be true for all of the tables we
currently iterate over, but not for all of the OnDiskHashTables we
currently use. For example, key_ and data_iterator would iterate over
meaningless data if they were used on the hash tables in PTHLexer.

We make the API safer by breaking this into two types. One doesn't
have the iterators, and the other must be told where the payload
starts.
