Remove size 1 from check as that isn't part of what the test is meant to be testing.

This test also runs on e.g. ARM-native builds when the X86 backend is also
built.  This test produces code for the default instruction set, even though it
is in a "X86" sub-directory. Given that this test doesn't seem to be testing
anything architecture-specific, it seems it's best to adapt the check to not
check for an architecture-dependent value (the size of the function), rather
than hard-code the test to target x86.
