Fix some bugs in llgs thread state handling.
* When the thread state coordinator is told to skip sending a stop request
for a running thread that is ignored (e.g. the thread that steps in a
step operation is technically running and should not have a stop sent
to it, since it will stop of its own accord per the kernel step operation),
ensure the deferred signal notification logic still waits for the
skipped thread. (i.e. we want to defer the notification until the
stepping thread is indeed stopped, we just don't want to send it a tgkill).
* Add ThreadStateCoordinator::RequestResumeAsNeeded(). This variant of the
RequestResume() method does not call the error function when the thread
is already running. Instead, it just logs that the thread is already
running and skips the resume operation. This is useful for the case of
vCont;c handling, where we tell all threads that they should be running.
At the place we're calling, all we know is "we want this thread running if
it isn't already," and that's exactly what this command does.
* Formatting change (minor) in NativeThreadLinux logging.

llgs: more work on thread stepping.
See https://github.com/tfiala/lldb/issues/75. Not fixed yet but
continuing to push this further.
Fixes:
* Resume() now skips doing deferred notifications if we're doing a
vCont;{c,C}. In this case, we're trying to start something up,
not defer a stop notification. The default thread action stop
mode pickup was triggering a stop because it had at least one
stop, which was wrong in the case of a continue. (Bug introduced
by previous change.)
* Added a variant to ThreadStateCoordinator to specify a set of
thread ids to be skipped when triggering stop notifications to
non-stopped threads on a deferred signal call. For the case of
a stepping thread, it is actually told to step (and is running)
for a brief moment, but the thread state coordinator would think
it needed to send the stepping thread a stop, which id doesn't
need to do. This facility allows me to get around that cleanly.
With this change, behavior is now reduced to something I think is
essentially a different bug:
* Doing a step into libc code from my code crashes llgs.
* Doing a next out of a function in my own code crashes llgs.

llgs: fix up some handling of stepping.
Tracked down while working on https://github.com/tfiala/lldb/issues/75.
This is not a complete fix for that issue, but moves us farther along.
Fixes:
* When a thread step is requested via vCont:{s,S}, Resume() now marks
the stepping thread as (1) currently stepping and (2) does trigger
the deferred signal for the stepped thread. This fixes a bug where
we were actually triggering a deferred stop cycle here for the non-stepping
thread since the single step thread was not part of the Resume()
deferred signal mechanism. The stepping thread is also marked in
the thread state coordinator as running (via a resume callback).
* When we get the SIGTRAP signal for the step completion, we don't
do a deferred signal call - that happened during the vCont:{s,S}
processing in Resume() already. Now we just need to mark that
the stepping thread is now stopped. If this is the last thread
in the set that needs to stop, it will trigger the process/delegate
stop call that will notify lldb. Otherwise, that'll happen when
the final thead we're waiting for stops.
Misc:
* Fixed up thread stop logging to use a leading 0 (0x%PRIx32) so
we don't get log lines like 0x5 for 0x05 SIGTRAP.

Revert "Add some overloads so that floating point literals can be AST matched properly."
Apparently the build bots get angry for some reason. Can't reproduce
that in a local cmake/ninja build. Will look closer. Rolling back for
now.

Add some overloads so that floating point literals can be AST matched properly.
I am not entirely sure whether the implemented sematics are ideal. In
particular, should floatLiteral(equals(0.5)) match "0.5f" and should
floatLiteral(equals(0.5f)) match "0.5". With the overloads in this
patch, the answer to both questions is yes, but I am happy to change
that.

PR 17421: Implemented -save-temps={obj|cwd} option
-save-temps=cwd is equivalent to -save-temps
-save-temps=obj saves temporary file in the same directory as output
This helps to avoid clobbering of temp files in case of parallel
compilation with -save-temps of the files that have the same name
but located in different directories.
