The Thumb2 conditional branch B<cond>.W has a different encoding (T3) to the unconditional branch B.W (T4) as it needs to record <cond>. As the encoding is different the B<cond>.W is given a different relocation type. ELF for the ARM Architecture 4.6.1.6 (Table-13) states that R_ARM_THM_JUMP19 should be used for B<cond>.W. At present the MC layer is using the R_ARM_THM_JUMP24 from B.W. This change makes B<cond>.W use R_ARM_THM_JUMP19 and alters the existing test that checks for R_ARM_THM_JUMP24 to expect R_ARM_THM_JUMP19. llvm-svn: 271997
