[modules] Refactor handling of -fmodules-embed-*. Track this properly rather
than reusing the "overridden buffer" mechanism. This will allow us to make
embedded files and overridden files behave differently in future.

[modules] Add -cc1 flag -fmodules-embed-all-files.

This flag causes all files that were read by the compilation to be embedded
into a produced module file. This is useful for distributed build systems that
use an include scanning system to determine which files are "needed" by a
compilation, and only provide those files to remote compilation workers. Since
using a module can require any file that is part of that module (or anything it
transitively includes), files that are not found by an include scanner can be
required in a regular build using explicit modules. With this flag, only files
that are actually referenced by transitively-#included files are required to be
present on the build machine.

[modules] Add an experimental -cc1 feature to embed the contents of an input
file in the .pcm files. This allows a smaller set of files to be sent to a
remote build worker when building with explicit modules (for instance, module
map files need not be sent along with the corresponding precompiled modules).

This doesn't actually make the embedded files visible to header search, so
it's not useful as a packaging format for public header files.

Global inline assembler blocks are merged before parsing, so no specific
location data is available. If pragma handling wants to look up the
position, it finds the LLVM buffer and wants to compare it with the
special built-in buffer, failing badly. Extend to the special handling
of the built-in buffer to also check for the inline asm buffer. Expect
only a single asm buffer. Sort it between the built-in buffers and the
normal file buffers.

Fixes the assert part of PR 22576.

Remove 'const' from MemoryBuffers used through the SourceManager

This removes a const_cast added in r211884 that occurred due to an
inconsistency in how MemoryBuffers are handled between some parts of
clang and LLVM.

MemoryBuffers are immutable and the general convention in the LLVM
project is to omit const from immutable types as it's simply
redundant/verbose (see llvm::Type, for example). While this change
doesn't remove "const" from /every/ MemoryBuffer, it at least makes this
chain of ownership/usage consistent.

[Allocator] Make the ContentCache object actually carry the 8-byte
alignment constraint rather than using the allocator function's over
alignment "feature". This was the only use of the "feature" which I plan
to remove next. =] Attaching the alignment to the type seems cleaner and
more principled anyways.
