perf symbols: Fix annotation of thumb code
In ARM's Thumb mode the bottom bit of the symbol address is set to mark
the function as Thumb; the instructions are in reality 2 or 4 byte on 2
byte alignments, and when the +1 address is used in annotate it causes
objdump to disassemble invalid instructions.
The patch removes that bottom bit during symbol loading.
Many thinks to Dave Martin for comments on an initial version of the
patch.
