Subject: [RFA/ARM 0/3] Add support for fused multiply-accumulate to ARM backend

All,

This sequence of three patches adds support to the ARM Backend for fused multiply-accumulate patterns on cores that support it.

Patch 1 adds floating-point support.
Patch 2 adds Advanced SIMD support in the auto-vectorizer.
Patch 3 adds intrinsic support in arm_neon.h.

These patches have been tested as a whole using QEmu targetting arm-none-eabi, and with an arm-linux-gnueabi bootstrap.

They require the ACLE feature test macros patch currently under review here:

Thanks,

Matt
