This changeset is a simple find and replace of `MOZ_FALLTHROUGH` and `[[fallthrough]]`.
Unfortunately, the MOZ_FALLTHROUGH_ASSERT macro (to assert on case fallthrough in debug builds) is still necessary after switching from [[clang::fallthrough]] to [[fallthrough]] because:
* MOZ_ASSERT(false) followed by [[fallthrough]] triggers a -Wunreachable-code warning in DEBUG builds
* but MOZ_ASSERT(false) without [[fallthrough]] triggers a -Wimplicit-fallthrough warning in NDEBUG builds.

This makes RAPL abort with more informative error messages if certain
kernel-provided files aren't present.

This removes the unnecessary setting of c-basic-offset from all
python-mode files.
This was automatically generated using
perl -pi -e 's/; *c-basic-offset: *[0-9]+//'
... on the affected files.
The bulk of these files are moz.build files but there a few others as
well.

tools/power/rapl.cpp:844:5 [-Wunreachable-code] code will never be executed
clang reports a -Wunreachable-code warning for sigemptyset() because Darwin's sigemptyset() is a macro that always returns 0. Thus `if (sigemptyset(&sa.sa_mask) < 0)` is always false and `Abort("sigemptyset() failed")` is never called. Linux's sigemptyset() can return 0 or -1. The extra parens around (0) suppress the clang warning.
This extracts the most useful browser-related measurements from rapl and
powermetrics.

The "gpu" and "ram" domains aren't supported by all platforms. rapl has a
special constant |kUnsupported_j| to represent this on Linux, but I
accidentally have a minus sign in front of it in several places, which means
that instead of printing "n/a" for unsupported planes we always print "1.0".
I think this happened because I used to hardwire -1 in there and then I later
changed it to a constant but forgot to remove the minus signs.
It sure would be nice to have automated testing for this stuff, but I don't see
how to do it.
The patch removes 455 occurrences of FAIL_ON_WARNINGS from moz.build files, and
adds 78 instances of ALLOW_COMPILER_WARNINGS. About half of those 78 are in
code we control and which should be removable with a little effort.
