[UpdateTestChecks] Teach the x86 asm parser to skip over the function

begin label emitted for some routines with personality functions and such. Without this, we don't even recognize such functions as appearing in the output and so don't attach any assertions to them. Happy to tweak this or improve it if folks w/ deeper knowledge of the asm sequences that show up here want. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@336987 91177308-0d34-0410-b5e6-96231b3b80d8
