This is the required alignment for Aarch64, and a number of other ABIs
prefer this size too when calling into system libraries.

This uses the JavaScriptCore assembler rev. 195098. It is tested on iOS
(for which it is disabled, as it only allows marking pages as executable when
running from Xcode). Testing on Linux will be done when hardware
arrives.

In 6572d4e50d73ac60a8974d07de74c27a7f99ebef we moved the
addressTempRegister to r10, and in
d8b276a59402cbbe6d070ba38805350e7f3dd8a1 we made sure that the YarrJIT
saves it too. JSC solved this by moving it to r6, which is already
saved by the YarrJIT. To make a future update of the assembler easier,
we also move it to r6.
This requires that we move our scratch register too. But, because it is
used a lot, we don't want it above r7 for Thumb2 reasons. Therefore, we
move the engine to r10, and the scratch register to r5.

Change 6572d4e50d73ac60a8974d07de74c27a7f99ebef moved the
addressTempRegister from r3 to r10, so that calculated calls would not
overwrite the fourth argument of a call. However, JSC's Yarr JIT might
also use it for certain loads, so it also needs to save r10.

All are conversions from size_t to int or to unsigned.

Try to avoid derefencing an empty vector, even when the result is not used.

We re-implemented Vector::begin() and end() by means of dereferencing the return
value from std::begin() and then taking the address of it. That causes a failing
assertion in MSVC's STL (rightly so!). We did this only to avoid modifying
the original YarrJIT.cpp code.
This patch instead simplifies our Vector.h stub again and just fixes the two
small occurrences in YarrJIT.cpp where it expects vector->begin() to return a
pointer instead of an iterator.

This brings in various bug fixes in the ARM and MIPS assemblers as well as
a Yarr crash fix and performance fix.
This change doesn't compile as-is, but the next change will
apply the modifications necessary to compile. That'll make future updates
easier as it allows for cherry-picking because the modifications are usually
always the same.
