Committed: Add testcases for a few PRs

These were fixed as part of the fix for PR 99766,
I thought it would be useful to add a few testcases
for the other cases that were failing.

Committed as obvious after running the tests to make
sure they work.

	PR rtl-optimization/100241
	PR rtl-optimization/99787

	* gcc.c-torture/compile/pr100241-1.c: New test.
