cmd/internal/obj/arm, runtime: delete old ARM softfloat code
CL 106735 changed to the new softfloat support on GOARM=5.
ARM assembly code that uses FP instructions not guarded on GOARM,
if any, will break. The easiest way to fix is probably to use Go
implementation on GOARM=5, like
MOVB runtime·goarm(SB), R11
CMP $5, R11
BEQ arm5
... FP instructions ...
RET
arm5:
CALL or JMP to Go implementation
