  -----------
  Fixed modifyData logic for offset values beyond +/- 1 MB.

When the offset is <-1MB/>+1MB, the appropriate sequence of instructions
needs to be generated to keep the PC-relative data access intact. The
previous logic was using the incorrect values for loading into the
temporary registers before using those registers as indirect pointers
(in the LDR/LDRSW case). This is now fixed.
