This reverts commit da6318a92fba793e4f2447ec478b001392d57d43.
This is causing failures on some build bots due to what appears
to be some kind of lit ordering dependency.
llvm-svn: 306833
Presently lit leaks files in the tests' output directories.
Specifically, if a test creates output files, lit makes no
effort to remove them prior to the next test run. This is
problematic because it leads to false positives whenever a
test passes because stale files were present. In general
it is a source of flakiness that should be removed.
This patch addresses this by building the list of all test
directories that are part of the current run set, and then
deleting those directories and recreating them anew. This
gives each test a clean baseline to start from.

Rather than relying on the gmlt-like data emitted into the .o/executable
which only contains the simple name of any inlined functions, use the
.dwo file if present.
Test symbolication with/without a .dwo, and the old test that was
testing behavior when no gmlt-like data was present. (I haven't included
a test of non-gmlt-like data + no .dwo (that would be akin to
symbolication with no debug info) but we could add one for completeness)
The test was simplified a bit to be a little clearer (unoptimized, force
inline, using a function call as the inlined entity) and regenerated
with ToT clang. For the no-gmlt-like-data case, I modified Clang back to
its old behavior temporarily & the .dwo file is identical so it is
shared between the two executables.
