Use struct stat::st_mtime instead of the underlying st_mtim, which is
called something different on Darwin.

Previously, each thread was assigned a fixed list of work, and the main
thread would block until every thread was finished, leading to most
cores sitting idle for the last few hundred milliseconds while a few
particularly long running threads would keep working. Use a single work
queue to evenly distribute load across the threads.

* changes:
versioner: use a virtual filesystem for input files.
versioner: cache -cc1 flags generated by the clang Driver.
versioner: refactor to use CompilerInstance directly.
Use an InMemoryFileSystem to store and share input files across
compilations.
This improves the result of `time versioner` further, from:
versioner 109.12s user 17.43s system 2433% cpu 5.201 total
to:
versioner 112.20s user 1.38s system 2416% cpu 4.700 total

Profiling showed that majority of time spent by versioner was being
spent in the x86 and x86_64 driver statting random files in /usr/lib,
looking for a toolchain. Hardcode a list of per-target flags which
correspond to a subset of the ones generated by clang, and use those
instead of calling out to Driver.
This changes the result of `time versioner` from:
versioner 156.57s user 1180.08s system 4109% cpu 32.525 total
to:
versioner 109.12s user 17.43s system 2433% cpu 5.201 total

This will make it easier to switch over to a virtual filesystem,
which should drastically improve performance.
This also fixes an issue with warning/error reporting.

Poking around with -Wundef exposed a pretty horrifying bug, so we
should probably keep it turned on.

Add an attribute that tells the preprocessor not to guard a
declaration, primarily for use with symbols that get reexported by
libc++ of the form `namespace std { using ::wctrans; }`.
