MIPS/GAS/testsuite: Split `branch-misc-2' tests into two

Move `branch-misc-2' tests for non locally-defined-global symbols into
separate files.  These tests have been introduced with:

commit 6f171daac941741e5fa904f6e462adb75a595495

<https://sourceware.org/ml/binutils/2003-03/msg00136.html>, ("On
resolving the MIPS gas branch reloc issue"), while the test case served
a different purpose.  With the original intent of the test case brought
back with:
