[binutils-gdb] MIPS16/GAS/testsuite: Add cross-section R_MIPS16_PC16_S1 relocation tests

https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;h=1f1e0a5d0eb8474321a1a6431b4171f67a438231

commit 1f1e0a5d0eb8474321a1a6431b4171f67a438231
Author: Maciej W. Rozycki <macro@mips.com>
Date:   Tue Feb 20 20:51:37 2018 +0000

    MIPS16/GAS/testsuite: Add cross-section R_MIPS16_PC16_S1 relocation tests
    
    Add a pair of MIPS16 branch tests to verify correct R_MIPS16_PC16_S1
    relocation generation for cross-section references in a single source.
    This complements commit c9775dde3277 ("MIPS16: Add R_MIPS16_PC16_S1
    branch relocation support").
