Symbols addressing Thumb code have zero bit set in st_value to distinguish them from ARM instructions. This caused wrong atoms' forming because of offset of one byte brought in by that corrected st_value. Fixed reading of st_value & st_value-related things in ARMELFFile while forming atoms. Symbol table generation is also fixed for Thumb atoms. Differential Revision: http://reviews.llvm.org/D7161 llvm-svn: 227174
