ipa: Add testcase for already fixed case [PR110705]

Browse source 
This testcase was fixed with r13-1695-gb0f02eeb906b63 which
added an Ada testcase for the issue but adding a C testcase
is a good idea and that is what this does.

Committed after making sure it passes on  x86_64-linux-gnu.

	PR ipa/110705

gcc/testsuite/ChangeLog:

	* gcc.c-torture/compile/pr110705-1.c: New test.
