[PATCH] libgcc SH: fix alignment for relaxation

Subject: [PATCH] libgcc SH: fix alignment for relaxation

when relaxation is enabled we can not infer the alignment
from the position as that may change. This should not change
non-relaxed builds as its allready aligned there. This was
the missing piece to building an entire toolchain with -mrelax

libgcc/
	* config/sh/lib1funcs.S (ashiftrt_r4_32): Increase alignment.
	(movemem): Force alignment of the mova intruction.
