I agree that matching "__thiscall" would be nicer, but that syntax
only works when -fms-extensions is enabled.

I think the better solution here is to figure out a way to suppress
printing the calling-convention when it's the default one for the ABI
and not explicitly specified by the user.

At least the tests are now precise enough that they won't silently
accept any new behaviour :)
