Generic function-alignment infrastructure.
Architectures can select FUNCTION_ALIGNMENT_xxB symbols; the FUNCTION_ALIGNMENT symbol is then set to the largest such selected size, 0 otherwise.
From this the -falign-functions compiler argument and __ALIGN macro are set.
This incorporates the DEBUG_FORCE_FUNCTION_ALIGN_64B knob and future alignment requirements for x86_64 (later in this series) into a single place.
NOTE: also removes the 0x90 filler byte from the generic __ALIGN primitive, that value makes no sense outside of x86.
NOTE: .balign 0 reverts to a no-op.
