Include the ARMv7 assembler in the qmldevtools bootstrap build
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.
