This adds a most recently used cache that can be used as a quick lookup table

XPCOM strings mark logically unused parts of nsStringBuffer as uninitialized
in debug builds by writing a marker byte and if memory checking is active,
by telling the memory checking that the range of memory is uninitialized.
This patch limits such marking to up to 16 code units to avoid quadratic
behavior, which is especially bad when there's a large disparity between
length and capacity (after a call to SetCapacity()).
The assumption here is that even a small poisoned memory range is enough
to detect the bugs that the poisoning is intended to detect.

clang can handle MSVC-like codepaths generally, so we want to use those
when building with clang for Windows. So we switch _MSC_VER over to _WIN32
to pick up those codepaths when compiling for Windows with clang.
Additionally, we relax the ordering of sections for the same scenario.
Note that we do need to tell clang to use -fms-extensions with the MSVC code,
we do that in the mingw clang build job patch.

GetPathFromURI() result is stored in an nsAutoCString, so it might as well return that type.

`result` may be empty or may be arbitrarily long, so I'll use nsCString inside the function.

Returning an UniquePtr, will remove std::move().
Also will `return s` instead of `return nullptr` when `(!s)`, to avoid extra construction which could also prevent elision (not entirely sure, but it's at least not worse!); and it's clearer that the two `return`s return the same already-constructed on-stack object.

nsAuto{,C}String -> ns{,C}String, will add std::move().
This allowed removals of 'AllowCompilerWarnings' from layout/painting,
netwerk/cookie, and toolkit/components/extensions.

MSVC doesn't like AssignLiteral(condition ? "literal1" : "literal2")
even when both literals have the same length. (clang and gcc are both
happy with that)

* Avoid the string implementation's capacity checks, since we know they
succeed.
* Avoid the string implementation's aliasing checks, since we know there's no
aliasing.
* Avoid writing the zero terminator more than once or out of sequence.
* Use u"" literals when appending literals to a UTF-16 string.
* Write runs of non-escaped code units instead of writing code unit by code
unit in order to benefit from SIMD (either via memcpy or
ConvertLatin1toUTF16).
This results in a 13% execution time reduction on desktop Haswell i7 when
getting the innerHTML of the body of the Selectors spec. (The WebKit
optimization target from https://bugs.webkit.org/show_bug.cgi?id=81214 .)

Nothing is using the xpt module anymore, which means we can remove it,
as well as the runtests.py script that runs its test, and the
integration of those tests in the build system.

This is the only reason I haven't used it before for things like
StyleSheet::State.
Change the underlying type to be the underlying enum representation by default,
but allow to override it if wanted.
Assertions should catch misuses.

Also rewrote some code around the actual problem to be more obviously correct

We move the XPConnect() singleton accessor to nsIXConnect to make it available for consumers outside of XPConnect. Most of the consumers of the singleton accessor just need the nsIXPConnect public interface, except for the IsShuttingDown() member which this patch adds to nsIXPConnect as well.

These properties were added in bug 478251 back when XPIDL was sort of emulating
WebIDL. They are not needed any more, and none of our XPIDL files use them.
