Nick Desaulniers 7c182ebab9 ARM: 9062/1: kprobes: rewrite test-arm.c in UAL ...

Clang's integrated assembler only accepts UAL syntax, rewrite the
instructions that were changed by RVCTv2.1.  The document "Assembly
language changes after RVCTv2.1" was very helpful.

  .syntax unified

directive is added, since -masm-syntax-unified is unreliable for older
but supported versions of GCC. See also:

commit fe09d9c641 ("ARM: 8852/1: uaccess: use unified assembler language syntax")
