On some of our arm targets, we get various -mfpu flags implicitly or explicitly passed to the compiler during test runs. The target options pushed in arm_neon.h that affect vmmlaq_s32 set isa_bit_neon, but the caller doesn't have that bit set, so arm_can_inline_p rejects the attempt to inline it, and the test fails.
An explicit -mfpu=neon would address the compile problem, but cause the assembler to reject the generated code. So this patch adds -mfpu=auto to the test, overriding any implicit flags with the fpu implied by the arch. Regstrapped on x86_64-linux-gnu, also tested on x-arm-wrs-vxworks7r2.
