Use alignment macros, pagesize and powerof2.
We are replacing all of the bespoke alignment code with
ALIGN_UP, ALIGN_DOWN, PTR_ALIGN_UP, and PTR_ALIGN_DOWN.
This cleans up malloc/malloc.c, malloc/arena.c, and
elf/dl-reloc.c. It also makes all the code consistently
use pagesize, and powerof2 as required.

Code size is reduced with the removal of precomputed
pagemask, and use of pagesize instead. No measurable
difference in performance.

No regressions on x86_64.
