    i386: Fix rtl checking ICE in ix86_elim_entry_set_got [PR112837]

    The following testcase ICEs with RTL checking, because it sets if
    XINT (SET_SRC (set), 1) is UNSPEC_SET_GOT without checking if SET_SRC (=
set)
    is actually an UNSPEC, so any time we see any other insn with PARALLEL
    and a SET in it which is not an UNSPEC we ICE during RTL checking or
    access there some other union member as if it was an rt_int.
    The rest is just small cleanup.

            * config/i386/i386.c (ix86_elim_entry_set_got): Before checking
            for UNSPEC_SET_GOT check that SET_SRC is UNSPEC.  Use SET_SRC a=
nd
            SET_DEST macros instead of XEXP, rename vec variable to set.

            * gcc.dg/pr112837.c: New test.
