It got disconnected during the cmake conversion. For Miscompilation.cpp,
it was purely advisory for the user and the ToolRunner.cpp version was
trying to compensate for libs and bins in the same directory, which
hasn't been the case for a very long time.

This replaces the threading of `std::string &Error` through all of
these APIs with checked Error returns instead. There are very few
places here that actually emit any errors right now, but threading the
APIs through will allow us to replace a bunch of exit(1)'s that are
scattered through this code with proper error handling.
This is more or less NFC, but does move around where a couple of error
messages are printed out.

We now use clang by default and fallback to gcc when requested.
With this commit, names reflect reality. No functional change
intended.
Discussed with: Rafael Espindola.

this, and in some circumstances (e.g. reducing particularly large test-cases)
this was causing bugpoint to be killed for hitting open file-handle limits.
No test case: I was only able to trigger this with test cases taking upwards of
10 mins to run.

This function is complementary to createTemporaryFile. It handles the case were
the unique file is *not* temporary: we will rename it in the end. Since we
will rename it, the file has to be in the same filesystem as the final
destination and we don't prepend the system temporary directory.
This has a small semantic difference from unique_file: the default mode is 0666.
This matches the behavior of most unix tools. For example, with this change
lld now produces files with the same permissions as ld. I will add a test
of this change when I port clang over to createUniqueFile (next commit).
