[committed] Remove compromised sh test

Surya's recent patch to IRA improves the code for sh/pr54602-1.c slightly.
Specifically it's able to eliminate a save/restore in the prologue/epilogue and
a bit of register shuffling.

As a result there literally aren't any insns that can be used to fill the delay
slot of the return, so a nop gets emitted and the test fails.

Given there literally aren't any insns to move into the delay slot, the best
course of action is to just drop the test.

gcc/testsuite
	* gcc.target/sh/pr54602-1.c: Delete test.
