target/arm/vfp_helper: Move code around

Browse source 
To ease the review of the next commit,
move the vfp_exceptbits_to_host() function directly after
vfp_exceptbits_from_host(). Amusingly the diff shows we
are moving vfp_get_fpscr().

Backports commit 20e62dd8c831c9065ed4a8e64813c93ad61c50d7 from qemu.
