[PATCH/AARCH64] Fix gcc.c-torture/compile/pr37433.c for AARCH64:ILP32.

[Andrew Pinski]

The problem here is that we get a symbol_ref which is SImode but for
the sibcall patterns we only match symbol_refs which use DImode.  I
added a new testcase that tests the non-value sibcall pattern too.

OK?  Bootstrapped and tested on aarch64-linux-gnu with no regressions.

Thanks,
Andrew Pinski

ChangeLog:

    * config/aarch64/aarch64.md (sibcall): Force call
    address to be DImode for ILP32.
    (sibcall_value): Likewise.

testsuite/ChangeLog:
    * gcc.c-torture/compile/pr37433-1.c: New testcase.
