Ok for trunk?

Since r16-5947-ga6c50ec2c6ebcb, gcc no longer uses a register for the
stack offset.  Adjust the expected assembler to use sp directly instead.

r16-5946-g83739ee76da65d produces:
stacktest1:
         sub     sp, sp, #8
         add     r3, sp, #6
         strh    r0, [r3]        @ __bf16
         ldrh    r0, [sp, #6]    @ __bf16
         add     sp, sp, #8
         bx      lr

r16-5947-ga6c50ec2c6ebcb produces:
stacktest1:
         sub     sp, sp, #8
         strh    r0, [sp, #6]    @ __bf16
         ldrh    r0, [sp, #6]    @ __bf16
         add     sp, sp, #8
         bx      lr

gcc/testsuite/ChangeLog:

        * gcc.target/arm/bfloat16_scalar_1_2.c: Adjust assembler to mach
        compiler.
        * gcc.target/arm/bfloat16_scalar_2_2.c: Likewise.
        * gcc.target/arm/bfloat16_scalar_3_2.c: Likewise.
        * gcc.target/arm/bfloat16_simd_1_2.c: Likewise.
        * gcc.target/arm/bfloat16_simd_2_2.c: Likewise.
        * gcc.target/arm/bfloat16_simd_3_2.c: Likewise.

OK.

Pushed as r16-7836-ge1ff04ffbe89c2.
