Using left shift on a uint8_t promotes it to a signed integer. If the shift is
large enough that the sign bit gets affected, we have undefined behavior. This
patch fixes this by first casting to uint32_t.

If the sets get too big we cannot allocate anything else, we'll just empty them
and invalidate the whole document.

People keep adding useless null-checks and it was not clear what the consensus
was from bug 1441165, but this should be unobjectionable I guess.

We compare two file ids to check the current process is launched from the same
executable. However, our telemetry showed a number of Win7 users failed to open
a file handle of the parent process with STATUS_OBJECT_PATH_NOT_FOUND even
though we opened a process handle and retrieved a module path of the parent
process successfully. We don't have data to explain how this happens or why
this happens only on Win7, Win10 10240, and 10586.
To mitigate this situation, this patch introduces a logic to compare NT path
strings. The benefit from doing this is 1) we don't have to open a file handle
of a parent process executable and 2) when we get an NT path, a network drive
or a symbolic link is already solved.
This new logic is much faster, but we still compare file ids on the first
attempt to minimize the impact. We fall back to the new logic only if we
detect the STATUS_OBJECT_PATH_NOT_FOUND failure.

Adds a module documentation in segment.rs giving an overview of the role of primitive segments and how they interact with clipping. Also reformatted the clip.rs documentation to play well with rustdoc.

During metrics initialization we load a few uncached glyph widths which can occasionally
show up in a profile. This should reduce the overhead of that somewhat.

Our implementation modified the state, in addition to throwing the exception.
And the tests not only didn't test for this, but wouldn't have reached that
code anyway, due to the harness giving up as soon as anything failed.

It doesn't really make sense to enforce this behavior for calls on stack
variables (which presumably we then want to do something with) and doesn't
necessarily make sense to enforce it for member variables either.

To avoid needing to access JSScript::realm() during finalization, we
associate the LCovSource* with a JSScript (if coverage is enabled). This
also saves memory by avoiding cloning the filename for each inner
function. One semantic change here is that the LCovRealm/Source is
allocated sooner than previously, but the result is the same.
