[PATCH, AArch64] Fix for LDR/STR to/from S and D registers

["Ian Bolton" <ian dot bolton at arm dot com>]

This is a fix for this patch:
http://gcc.gnu.org/ml/gcc-patches/2013-04/msg01621.html

If someone compiles with -mgeneral-regs-only then those instructions
shouldn't be used. We can enforce that by adding the fp attribute to
the relevant alternatives in the patterns.

Regression tests all good.

OK for trunk?

Cheers,
Ian

* config/aarch64/aarch64.md (movsi_aarch64): Only allow to/from
S reg when fp attribute set.
(movdi_aarch64): Only allow to/from D reg when fp attribute set.
