Bug 1832708 - Disable std::__throw_* wrapping on libc++ >= 14.0. r=firefox-build-system-reviewers,andi

As of libc++ 14, the functions are defined in the std namespace rather
than std::<something>, which makes them conflict with our wrapping. This
is not a problem on libstdc++ because the functions are defined in the
library itself rather than the headers.

This was the real reason behind the addition of #ifndef __wasm__ ; this
is a more generic fix for the same problem.

Differential Revision: https://phabricator.services.mozilla.com/D170840

Improve the chance that we catch memory errors with PHC by:

 * Increasing the number of PHC slots (increased from 64 to 4096 in most
   cases).
 * Lower the delay for the first PHC allocation, with more slots we can
   afford to trap allocations from earlier in Firefox's startup.

These improve the chance PHC has of catching an error by 64x, at the cost of
additional 1MB of allocation metadata (on 4KB page size systems).  It
shouldn't impact performance more than having PHC on at all.

This patch was originally developed by Randell Jesup.

Bug 1792146: Make replace_malloc_usable_size succeed with pointers within allocation pages. r=glandium

This changes replace_malloc_usable_size to allow measuring the size of
ptrs that appear anywhere within an allocation page, not just ptrs to the
start of the allocation pages.

This also modifies a gtest to explicitly check the usable size of some
modified pointers, not just the usable size of the pages where those
pointers are located.

Bug 1779257 - Fix the stack walking for linux markers by calling getcontext in a valid stack frame r=mstange

See my comment on here for more context of my investigation:
https://bugzilla.mozilla.org/show_bug.cgi?id=1779257#c9

The saved context is invalid once the function that called `getcontext`
returns. We need to call the `getcontext` while the frame where we called it is
still on the stack. That's why this patch is moving the call to `getcontext` to
parent function by inlining the SyncPopulate content by using a macro instead.
This has to be a macro instead of a function because stack pointer address will
be invalid once the `Registers::SyncPopulate` returns. I tried to change this
method to inline but that didn't help either.

The system calls of releasing a chunk of memory can be costly and should be
done outside the arena lock's critical section so that other threads aren't

Some of the runtime options are compiled-in constants when MOZ_DEBUG is not
defined.  But it can be useful to enable these configuration options without
enabling the rest of MOZ_DEBUG (eg assertions).  This patch adds a new
preprocessor macro to enable runtime configuration.
