MallocBench record/replay should support realloc
https://bugs.webkit.org/show_bug.cgi?id=131598

Reviewed by Ryosuke Niwa.

* MallocBench/MallocBench.xcodeproj/project.pbxproj: Fixed some linkage
issues that caused us not to fully link to system malloc in the default
case. Also marked mbmalloc.dylib as required so the error message will
be clearer if we mess up.

* MallocBench/MallocBench/Interpreter.cpp:
(Interpreter::run):
* MallocBench/MallocBench/Interpreter.h: Added the realloc case, and
upgraded one-letter names to full words.

Fixed some mbmalloc exports
https://bugs.webkit.org/show_bug.cgi?id=131599

Reviewed by Ryosuke Niwa.

* bmalloc.xcodeproj/project.pbxproj: Made some headers a private part
of the project, so we can call them from API.

* bmalloc/mbmalloc.cpp: Marked the mbmalloc functions with default
visibility, so they show up as exported in the .dylib.
