jemalloc_ptr_info() gives info about any pointer, such as whether it's within a
live or free allocation, and if so, info about that allocation. It's useful for
debugging.
moz_malloc_enclosing_size_of() uses jemalloc_ptr_info() to measure the size of
an allocation from an interior pointer. It's useful for memory reporting,
especially for Rust code.

Bug 1186064 removed most of it when we started requiring VS 2015u2, but
the "frex" function exported through mozglue.def.in was only used
through the MSVCRT being patched by fixcrt.py, which is not done anymore.
So the "frex" export is not used anymore, and so the "dumb_free_thunk"
function is not used anymore as well.

MOZ_REPLACE_MALLOC_LINKAGE was added back when there were problems with
getting weak references working properly for replace-malloc.
Versions of OSX < 10.6 needed flat namespace, but aren't supported
anymore.
Versions of Xcode < 4.5 required flat namespace + a dummy library in
order to produce proper weak references. There is virtually nobody still
building with such an ancient toolchain.
Keeping those around doesn't /really/ hurt, except recent versions of
Xcode don't expose dyldinfo in /usr/bin, used for the configure test.
Consequently, MOZ_REPLACE_MALLOC_LINKAGE ended up being set to use the
dummy library setup, which, by using flat namespace, now causes harm in
bug 1356701, causing bug 1378332.

This patch reduces the differences between builds where the profiler is enabled
and those where the profiler is disabled. It does this by removing numerous
MOZ_GECKO_PROFILER checks.
These changes have the following consequences.
- Various functions and classes are now defined in all builds, and so can be
used unconditionally: profiler_add_marker(), profiler_set_js_context(),
profiler_clear_js_context(), profiler_get_pseudo_stack(), AutoProfilerLabel.
(They are effectively no-ops in non-profiler builds, of course.)
- The no-op versions of PROFILER_* are now gone. The remaining versions are
almost no-ops when the profiler isn't built.

EnsureWalkThreadReady takes two locks, one in _beginthreadex and another in the DLL hook setup.
We can avoid the first by not calling EnsureWalkThreadReady if we're walking a suspended thread, since we won't be using a separate WalkThread anyway.
To avoid the hook locks, I gave in and decided to go back to setting up the hooks in DllBlocklist_Initialize as originally planned.
This avoids many additions of `extern "C"` in C++ code and will avoid
having to do the same to mozjemalloc once built as C++.

aarch64's gcc and arm's gcc with -mfpu=neon defines __ARM_NEON for NEON, so we should detect it to support NEON code.

This will prevent the profiler from suspending a target thread while that thread holds the RtlLookupFunctionEntry lock, which the profiler itself also wants to use.
Everything depending on the widget being gonk can go away, as well as
everything depending on MOZ_AUDIO_CHANNEL_MANAGER, which was only
defined on gonk builds under b2g/ (which goes away in bug 1357326).
