tree-optimization/110556 - tail merging still pre-tuples
The stmt comparison function for GIMPLE_ASSIGNs for tail merging
still looks like it deals with pre-tuples IL. The following
attempts to fix this, not only comparing the first operand (sic!)
of stmts but all of them plus also compare the operation code.
PR tree-optimization/110556
* tree-ssa-tail-merge.cc (gimple_equal_p): Check
assign code and all operands of non-stores.
* gcc.dg/torture/pr110556.c: New testcase.
