Improve performance of ByteStringFromAscii by changing kHexValue to have -1 in invalid value slots. This way a single load can do both the validation and conversion.

4ef66c72aedf135f2b4fd0ba7a73de6642decfff by Abseil Team <absl-team@google.com>:

Eliminate an unnecessary load when futex is contended in Waiter::Wait()

The first argument to compare_exchange_weak() is a reference and will be
updated upon failure.  There is no need to do an additional load on the
same variable.
