This change introduces two fixes. The second fix allows to generate a test to check the first fix. - Output `CHECK-EMPTY` prefix for an empty line in ASM output. Before that fix `update_llc_test_checks.py` incorrectly emits `CHECK-NEXT: <space>` prefix. - Fix the `ASM_FUNCTION_MIPS_RE` regex to stop on a real function epilogue not on an inline assembler prologue and include inline assembler code into a test.
