[ARM] Preserve fpu behaviour for '-crypto'
Summary: This patch restores the behaviour that -fpu overwrites the
architecture obtained from -march or -mcpu flags, not enforcing to
disable 'crypto' if march=armv7 and mfpu=neon-fp-armv8. However, it does
warn that 'crypto' is ignored when passing mfpu=crypto-neon-fp-armv8.
