tree-ssa-sink: do not touch calls that return twice
Avoid moving pure/const calls that may return twice in tree-ssa-sink:
properly redirecting the associated abnormal edge is non-trivial.
gcc/ChangeLog:
PR tree-optimization/107505
* tree-ssa-sink.cc (statement_sink_location): Additionally
reject ECF_RETURNS_TWICE calls.
gcc/testsuite/ChangeLog:
PR tree-optimization/107505
* gcc.dg/pr107505.c: New test.
