With more tests added to LLVM libc each week we want to keep track of unittest's runtime, especially for low end build bots.
Top offender can be tracked with a bit of scripting (spoiler alert, mem function sweep tests are in the top ones)
```
ninja check-libc | grep "ms)" | awk '{print $(NF-1),$0}' | sort -nr | cut -f2- -d' '
```
Unfortunately this doesn't work for hermetic tests since `clock` is unavailable.

The old code, which has regressed over many cleanups, has been replaced
with the new wide integer to hex string facility.

We compare this type in the string_test. It had no specialization here
so it could cause linker errors. This patch simply extends the interface
to support it.

A convenience wrapper name `add_libc_test` is also added which adds both
a unit test and a hermetic test. The ctype tests have been switched over
to use add_libc_test.

This part of the effort to make all test related pieces into the `test`
directory. This helps is excluding test related pieces in a straight
forward manner if LLVM_INCLUDE_TESTS is OFF. Future patches will also move
the MPFR wrapper and testutils into the 'test' directory.
