[PATCH, ARM] Remove redundant TARGET_VFP

["Richard Earnshaw (lists)" <Richard dot Earnshaw at arm dot com>]

Now that it is clear that TARGET_VFP is a constant we can clean it up
and remove it entirely.

This revealed one problem.  The test in arm_expand_vfp_builtin was
essentially a NOP.  It should, instead, have been testing TARGET_HARD_FLOAT.

Tested on arm-none-eabi and installed on trunk.
