This commit moves the register allocator out of midgard_compile.c and
into its own midgard_ra.c file. In doing so, a number of dependencies
are identified and moved into their own files in turn. midgard_compile.c
is still fairly monolithic, but this should help.
Code churn, but no functional changes should be introduced by this
commit.
