For example this would pass argument validation even though the mandatory **address** and **count** arguments are missing:

Part of the problem was that an empty string was considered a valid value for a mandatory argument, which didn't make much sense.

[LAA] Fix estimation of number of memchecks
Summary:
We need to add a runtime memcheck for pair of accesses (x,y) where at least one of x and y

Assuming we have w writes and r reads, currently this number is estimated as being
w* (w+r-1). This estimation will count (write,write) pairs twice and will overestimate
the number of checks required.
This change adds a getNumberOfChecks method to RuntimePointerCheck, which
will count the number of runtime checks needed (similar in implementation to
needsAnyChecking) and uses it to produce the correct number of runtime checks.
Test Plan:

[cmake] [OCaml] Make ocamldoc targets depend on output files
OCaml doc builds fail without .cmi files, and .cmi files are collected

well.
