Original change's description:
> [vm] Remove tcmalloc and malloc profiler.
>
> The standalone VM originally began statically linking tcmalloc to work around bugs in the system malloc for Fiber. Later it used tcmalloc's hooks to implement a profiler, but this is rarely used since it is only available in debug mode, misses early allocations, and often misses late allocations from an exhausted sample buffer. Removing it altogether avoids build complexity around which combinations of compiler/architecture/sysroot support tcmalloc, and reduces binary size.
