lib/libm: Use __asm__ instead of asm.

`asm` is not part of the C standard and causes a complier error when
`-std=c99` is used. `__asm__` is the recommended alternative.

stm32: Use hardware double sqrt on F7/H7 MCUs.

Identical to cd527bb324 but for doubles.
This gives a -2.754% improvement on bm_float.py, and -35% improvement on
calling sqrt in a loop.
