[arm] Fix use of CRC32 intrinsics with Armv8-a and hard-float

Backport from mainline
2019-08-22  Kyrylo Tkachov <kyrylo.tkachov@arm.com>

* config/arm/arm_acle.h: Use arch=armv8-a+crc+simd pragma for CRC32
intrinsics if __ARM_FP.
Use __ARM_FEATURE_CRC32 ifdef guard.

* gcc.target/arm/acle/crc_hf_1.c: New test.
