[PATCH] [PR testsuite/67959]Minor cleanup for ssa-thread-13.c

[Jeff Law]

The enum rtx_code bitfield causes grief for arm-eabi.  Given the test 
doesn't actually care about the size of that field, the easiest fix was 
just to make it a simple integer.

Tested on both x86_64-linux-gnu and arm-eabi to ensure the updated test 
passes on both targets.

Installed on the trunk.
