Hi,
  I found some more testcases that would cause an internal compiler
error while working on my bit-field lowering pass.  Since there was no
testcase already done, I thought it would be best if it was applied to
the trunk.

Thanks,
Andrew Pinski

testsuite/ChangeLog:
* gcc.c-torture/compile/20200105-1.c: New testcase.
* gcc.c-torture/compile/20200105-2.c: New testcase.
* gcc.c-torture/compile/20200105-3.c: New testcase.
