Hi all,
  While working on implementing lowering of bit-field accesses in
gimple, I ran into an ICE which was not covered by the current
testsuite.

Committed these two new testcases as obvious.

Thanks,
Andrew Pinski

ChangeLog:
* gcc.c-torture/compile/20191015-1.c: New test.
* gcc.c-torture/compile/20191015-2.c: New test.
