Reimplement getToken and SplitString as "StringRef helper functions"

separator chars and skips leading seperators.

performance back down to acceptable-for-diagnostics levels, even for
long doubles.

Provide dbgs(), a circular-buffering debug output stream. By default it

simply passes output to errs(). If -debug-buffer-size=N is set N > 0,
