bit_cast should never be used on pointers, as it doesn't avoid UB and
can lose qualifiers.
Fortunately, the only use of bit_cast on a pointer was to cast
nullptr into a function pointer, and because nullptr will implicitly
behave as any kind of pointer, that cast isn't needed.

These are slightly frustrating. First, when a struct is packed, some of
its fields may be underaligned. This is fine for direct access
(foo.bar), but if one takes the address if the field, this creates an
unaligned pointer. Dereferencing that pointer is then UB. (I'm not sure
if creating that pointer is UB.)
Crashpad seemingly doesn't do this, but it uses EXPECT_EQ from GTest.
EXPECT_EQ seems to internally take pointers to its arguments. I'm
guessing it binds them by const reference. This then trips UBSan. To
avoid this, we can copy the value into a temporary before passing to
EXPECT_EQ.
Second, the test to divide by 0 to trigger SIGFPE is undefined behavior.
The compiler is not actually obligated to trip SIGFPE. UBSan prints one
of its errors instead. Instead, since this file is only built on POSIX
anyway, use GCC inline assembly to do the division. That one is
well-defined.
Finally, casting a string to uint32_t* is undefined both by alignment
and by strict aliasing (although Chromium doesn't enable the latter).
Instead, type-punning should be done with memcpy.

This is a follow-up to 0fc1b6ae780e7ba854652bd5581f936abf824a5e.
The change in macOS 14's dyld to insert new modules in the front of
`dyld_all_image_infos` means that if any images are loaded after the
executable and its direct dependencies, it's no longer possible to
rotate the list to match the order used by the `dyld_get_image...`
APIs.
This forces us to dispense with checking the order at all except to
ensure that the executable is first, and dyld itself is last.
Additionally fixes an unreachable return introduced in
0fc1b6ae780e7ba854652bd5581f936abf824a5e.

dyld in macOS 14 has two changes that impact how we read in modules:
- Timestamp is always empty
- The executable appears *last* rather than first in the
dyld_all_image_infos array (see comment for details)
This change:
- Removes all timestamp checks in the tests
- Removes 10.6 era code that worked around a different "executable in
the wrong place" issue. Replaces this with a new branch that checks
if the executable is in the last position, and rotates it to the
front if so. This is necessary instead of just swapping (as in the 10.6
code) so that it can match the order returned by the `dyld_get_image...` family.

WebView makes use of this allowlist. We are hoping to

it is impractical to indefinitely add a larger list of switch

This CL adds a scoped handler for such registrations and
uses it on Windows crashpad client. To allow this to
be stored, RegisterHandler() on the client needs to move
