So this can be seen in the new vadcq* , vsbcq* tests:

**    ...
**    vmrs    (?:ip|fp|r[0-9]+), FPSCR_nzcvqc(?:    @.*|)
**    ...
**    bfi    (?:ip|fp|r[0-9]+), (?:ip|fp|r[0-9]+), #29, #1(?: @.*|)
**    ...
**    vmsr    FPSCR_nzcvqc, (?:ip|fp|r[0-9]+)(?:    @.*|)
**    ...

The fact that there's a BFI there rather than the BIC + ORR shows
that this has now been optimised by the compiler and the bug isn't
present in those intrinsics any longer... Sorry, I should have linked
that in better in our patch series!

Added a runtest, also, as it was fairly trivial to write it out :)

Thanks,
Stam
