d30d4a080d perf tools: Remove unnecessary ctype.h inclusion 
There are unnecessary #include <ctype.h> out there, and they might cause
a nasty build failure in some environment. As we already have most of
ctype macros in util.h, just get rid of them.

A few of exceptions are util/symbol.c which needs isupper() macro util.h
doesn't provide and perl scripting support code which includes ctype.h
internally.

e3e877e79b perf bench: Allow passing an iteration count to "bench mem mem{cpy,set}" 
"perf stat ... perf bench mem mem..." is pretty meaningless when using
small block sizes (as the overhead of the invocation of each test run
basically hides the actual test result in the noise). Repeating the
actually interesting function's invocation a number of times allows the
results to become meaningful.

be3de80dc2 perf bench: Also allow measuring memset() 
This simply clones the respective memcpy() implementation.
