It's not being used afaict, and is completely untested. If someone
wants to use QML on SH4, the interpreter will have to do.

-typedef "Jump" may not be used in an elaborated type specifier
-explicit specialization of function must precede its first use
-"Value" is ambiguous

Even when the C++ target is not ARMv7 we want to include it in order to
be able to generate QML cache files with code ahead of time.
This requires a few changes:
* The Jump classes need to move from the AbstractMacroAssembler
super-class into the concrete assembler sub-class, in order to
use it in specializations.
* Some of the template specializations in LinkBuffer for example or
for platform dependent operations need to be pre-processor enabled
when bootstrapping
* The generic loadPtr/addPtr etc. functions need to move to the concrete
assemblers to be able to call the correct 32-bit or 64-bit variations.
* We need to force what looks like a loss of precision to the compiler
in the 32-bit ARMv7 linking code when linking jumps.
Finally then we can explicitly instantiate at least QV4::JIT::Assembler
for ARMv7 when bootstrapping. Currently only on x86-64 hosts, but that
is a temporary limitation.

Since the #ifdef for ARMv7 and ARM64 makes it impossible to cross
compile, we need to replace it with a template specialization of
LinkBuffer. The "old" LinkBuffer becomes LinkBufferBase, then there's a
generic LinkBuffer that's a sub-class of LinkBufferBase. Then there's a
BranchCompactingLinkBuffer template that implements the compaction and
two ARMv7 and ARM64 specializations of LinkBuffer<T> end up being
sub-classes of BranchCompactingLinkBuffer instead of LinkBufferBase.

Unfortunately the link buffer depends on target platform types.

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.

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.
