Accept immediate comments in x86(_64) assembly
Objdump can sometimes output comments after assembly instructions,
which are then not recognised as an instruction that alters the
stack, by check_cfi.py. For example objdump might output the
following when increasing the frame size on x86_64:
subq $0x108, %rsp # imm = 0x108
Fix this by recognising and accepting assembly comments in this form:
"# imm = 0x..." which may be postfixed to stack altering instructions
from objdump.
Note: objdump does not currently output these comments however
subsequent changes to quick entrypoint assembly could result in these
comments being added.
Test: ./art/tools/check_cfi.py (on x86 and x86_64 targets)
