- In Python 2.x, basestring is the base string type, but in
Python 3.x basestring is not defined and instead str includes
unicode strings.
- When Python is in a path that includes spaces, it needs to
be specified with quotes in the test files for it to run.
- The cache.ll test relies on files of a specific size being
created by Python, but on some versions of Windows the
files that are created by the current code are one byte
larger than expected. To fix the test, update file creation
to always make files of the expected size.

- thinlto_codegen_set_cache_size_bytes to control the absolute size of cache directory.
- thinlto_codegen_set_cache_size_files the size and amount of files in cache directory.
These functions have been supported in C++ LTO API for a long time, but were absent in C LTO API.

borked by: rL284966 (see: https://reviews.llvm.org/D25730).
Previously, Interval was unsigned (see: CachePruning.h), replacing the type with std::chrono::seconds (which is signed) causes a regression in behaviour because the c-api intends negative values to translate to large positive intervals to *effectively* disable the pruning (see comments on: setCachePruningInterval()).

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).

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.

Clang always emit a hash for ThinLTO, but as other frontend are
starting to use ThinLTO, this could be a serious bug.

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.

This reverts;
r269548, "XFAIL ThinLTO Caching test on Windows."

This reverts commit r269538 and r269542.
"rename()" is expected to fail across filesystems, will handle this.
