[PATCH, testsuite]: Add x86_64 to gcc.dg/debug/dwarf2/const-2b.c target selector

[Uros Bizjak]

2016-09-22  Uros Bizjak  <ubizjak@gmail.com>

    * gcc.dg/debug/dwarf2/const-2b.c: Also compile for x86_64-*-*.
    Remove SSE effective target requirement.

Tested on x86_64-linux-gnu {,-m32} where the testcase currently fails
for unrelated reasons.

Committed to mainline SVN.

Uros.
