InstrProf: Read unsigned numbers with strtoul and strtoull
Fixes a bug where unsigned numbers are read using strtol and strtoll.
I don't have a testcase because this bug is effectively unobservable
right now. To expose the problem in the hash, we would need a function
with greater than INT64_MAX counters, which we don't handle anyway. To
expose the problem in the function count, we'd need a function with
greater than INT32_MAX counters; this is theoretically observable, but
it isn't a practical testcase to check in.
An upcoming commit changes the hash to be non-trivial, so we'll get some
coverage eventually.
