StringRef - Represent a constant reference to a string, i.e.
a character array and a length, which need not be null terminated.
This class does not own the string data, it is expected to be used in situations where the character data resides in some other buffer, whose lifetime extends past that of the StringRef. For this reason, it is not in general safe to store a StringRef.

Parse the current string as an integer of the specified radix.
If Radix
is specified as zero, this does radix autosensing using extended C rules: 0 is octal, 0x is hex, 0b is binary.
If the string is invalid or if only a subset of the string is valid, this returns true to signify the error. The string is considered erroneous if empty or if it overflows T.
