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.

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.

It turns out that in QML it is not unusual that during early binding
evaluations due to the undefined order, the evaluation tries to look up
properties in objects that aren't initialized yet and thus exceptions are
thrown. Eeach thrown exception saves a stack trace, which is expensive to
generate when using the JIT, as it does full stack unwinding.
This patch implements a more light-weight approach by storing the instruction
pointer in the context before leaving JIT generated code.
