Keith Randall 69aed4712d cmd/compile: use better splitting condition for string binary search
Currently we use a full cmpstring to do the comparison for each
split in the binary search for a string switch.

Instead, split by comparing a single byte of the input string with a
constant. That will give us a much faster split (although it might be
not quite as good a split).

Fixes #53333

R=go1.20
