[committed] [PR target/85993] Remove dead conditional in SH target code

[Jeff Law]

Per Oleg's comment in the PR, the second block is dead and should be
removed...

Committing to the trunk.   While I'm confident this won't change
anything, my tester will bootstrap sh4 & sh4eb overnight for additional
verification.
