Add a macro to annotate function end and start using both ENTRY and END
for each function. This allows valgrind (and presumably other debugging
tools) to use the debug symbols to trace the functions.

Reference results of the experiments on Qualcomm MSM7x25 (524MHz):

[original C code]
prc thr usecs/call samples errors cnt/samp
size
strcpy_1k 1 1 14.56159 99 0 1000
1024

[ARM optimized code]
prc thr usecs/call samples errors cnt/samp
size
strcpy_1k 1 1 3.46653 99 0 1000
1024

The work was derived from ARM Ltd.
