Subject: Work around a weird optimization bug in armhf
Without this patch, compilation on armhf fails with
```
/tmp/ccJsRMs3.s: Assembler messages:
/tmp/ccJsRMs3.s:21403: Warning: base register written back, and overlaps one of transfer registers
/tmp/ccJsRMs3.s:28133: Error: registers may not be the same -- `str r3,[r3],#4'
/tmp/ccJsRMs3.s:28971: Warning: base register written back, and overlaps one of transfer registers
```
on gcc-4.9.4. See
https://buildd.debian.org/status/fetch.php?pkg=starlink-ast&arch=armhf&ver=8.0.2%2Bdfsg-1&stamp=1414223014
as example.
The error appears with MAKE_MASK(F, float), while the warnings are
with MAKE_MASK(D, double) and MAKE_MASK(LD, long double).
