Account for calling convention specifiers in function definitions in IR test cases

Several tests wouldn't pass when executed on an armv7a_pc_linux triple
due to the non-default arm_aapcs calling convention produced on the
function definitions in the IR output. Account for this with the
application of a little regex.

Patch by Ying Yi.
