Peter Collingbourne 7faa60c406 llvm-lto2: Move the LTO::run() action behind a subcommand.
Move LTO::run() to a "run" subcommand so that we can introduce new subcommands
for testing different parts of the LTO implementation.

This doesn't use llvm::cl subcommands because it doesn't appear to be currently
possible to pass an argument not associated with a subcommand to a subcommand
(e.g. -lto-use-new-pm, -mcpu=yonah).

Peter Collingbourne 25a17ba4c7 Support, LTO: When pruning a directory, ignore files matching a prefix.
This is a safeguard against data loss if the user specifies a directory
that is not a cache directory. Teach the existing cache pruning clients
to create files with appropriate names.

Mehdi Amini f82bda0a7a ThinLTO: don't perform incremental LTO on module without a hash
Clang always emit a hash for ThinLTO, but as other frontend are
starting to use ThinLTO, this could be a serious bug.

Mehdi Amini adc0e26bef [ThinLTO] Add caching to the new LTO API
Add the ability to plug a cache on the LTO API.
I tried to write such that a linker implementation can
control the cache backend. This is intrusive and I'm
not totally happy with it, but I can't figure out a
better design right now.

NAKAMURA Takumi c50a2a93ae Rework r269548, "XFAIL ThinLTO Caching test on Windows.", not to use XFAIL, for now.
It was passing (and is XPASSing) with --host=linux --target=win32.

Mehdi Amini 34b0241b81 Revert "Add testing in llvm-lto for ThinLTO caching."
This reverts commit r269538 and r269542.
"rename()" is expected to fail across filesystems, will handle this.
