This CL expands the ASCII short circuit to add the number range and _
into IsXIDContinue.
IsXIDStart is updated to filter out anything less then the first
sequence after the (a-zA-Z) blocks as they won't be XIDStart but do cover
all of the common ASCII punctuation characters.

Our common case is ASCII characters but, because those come at the start
of the XID Start range they'll end up being checked _last_ as we binary
search through the range. This means we're getting the worst case
behaviour for our common character.
This CL adds a quick check for [a-zA-Z] at the start of IsXIDStart to
quickly determine if we're an ascii character.

This CL updates the clang format files to have a single shared format
between Dawn and Tint. The major changes are tabs are 4 spaces, lines
are 100 columns and namespaces are not indented.

Invalid UTF-8 was being best-effort consumed, which given the right sequence of brokenness, could end up with diagnostic locations referring to bytes beyond the end of a line.
Improve the UTF-8 decoding so that it can detect when multi-byte codepoints are missing the high-bit being set.
Actually detect this in a lexer, and parser and produce errors.
