Fix build for QNX

2015-10-15T10:22:57+00:00

The QNX target appears to be unable to accept ALWAYS_INLINE used as the
sorting function in std::sort, so let it be normal inline there.

Fix lots of crashes because of 4th argument register trampling.

Reviewed by Michael Saboff.

r3 register is the 4th argument register for ARM and also a scratch
register in the baseline JIT for this architecture. We can use r6
instead, as this used to be the timeoutCheckRegister and it is no
longer used since r148119.

* assembler/ARMAssembler.h: Temp register is now r6 instead of r3 for ARM.
* assembler/MacroAssemblerARMv7.h: Temp register is now r6 instead of r3 for ARMv7.
* dfg/DFGGPRInfo.h: Add r3 properly in GPRInfo for ARM.
* jit/JITStubs.cpp: Remove obsolete timeoutCheckRegister init.
* yarr/YarrJIT.cpp: Use r3 and not the new scratch register r6 and r8 register
doesn't need to be saved.

Do not use unaligned access when disabled

2014-10-30T10:50:39+00:00

Use the GCC feature defines to check for support for ARMv6 style
unaligned access support. This fixes configurations where it was
disabled and the ARMv6-M processors where it is not supported.
