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").
