disabled fixing of calls to non-function entries.  this is likely caused by mis-identification of functions and not a real reason to pin things

updated to elide setting address to 0 when applying pcrel reloc.  pcrel reloc now ignores virtualOffset field

minor fixes for instructions that are likely bogus (i.e., pcrel insns that access out-of-bounds memory)

adjusted pcrel relocs to handle memory operands properly after breaking it for handling arm reg operations
