A significant number of our tests in C accidentally use functions
without prototypes. This patch converts the function signatures to have
a prototype for the situations where the test is not specific to K&R C
declarations. e.g.,
void func();
becomes
void func(void);
This is the twelfth batch of tests being updated (the end may be in
sight soon though).

Now that the legacy PM is deprecated for the optimization pipeline, we
can start deleting legacy PM tests.
For tests that test both PMs, merge the RUN lines.
Delete tests specific to the legacy PM.

This fails due to the clang invocation running at -O0, producing an optnone function.
Then even with -O2 in the later invocations, LoopVectorizePass doesn't run on the optnone function.
So split this into an -O0 run and an -O2 run.

As per the discussion on D58375, we disable test that have optimizations under
the new PM. This patch adds -fno-experimental-new-pass-manager to RUNS that:
- Already run with optimizations (-O1 or higher) that were missed in D58375.
- Explicitly test new PM behavior along side some new PM RUNS, but are missing
this flag if new PM is enabled by default.
- Specify -O without the number. Based on getOptimizationLevel(), it seems the
default is 2, and the IR appears to be the same when changed to -O2, so
update the test to explicitly say -O2 and provide -fno-experimental-new-pass-manager`.

Summary:
The opt level was not being passed down to the ThinLTO backend when
invoked via clang (for distributed ThinLTO).
This exposed an issue where the new PM was asserting if the Thin or
regular LTO backend pipelines were invoked with -O0 (not a new issue,
could be provoked by invoking in-process *LTO backends via linker using
new PM and -O0). Fix this similar to the old PM where -O0 only does the
necessary lowering of type metadata (WPD and LowerTypeTest passes) and
then quits, rather than asserting.

Recommit of r317951 and r317951 along with what I believe should fix
the remaining buildbot failures - the target triple should be specified
for both the ThinLTO pre-thinlink compile and backend (post-thinlink)
compile to ensure it is consistent.

This reverts commit r317951 and r317952. The new test is aborting on
some bots and I'll need to investigate later.

Should fix test added in r317951.
