Chris Tate ea4d570e59 Speed up split, indexOf, slice and Number() on ASCII fields ...

Number() of a string with an optional sign and 1 to 15 digits returns
the integer directly; every other string keeps the full StringToNumber
grammar, out of line.

split() with a separator collects its first batch of pieces before
creating the result, so the result is an inline array of exactly that
size, filled in place. A split's default limit skips the uint32
conversion, and pieces of a proven-ASCII string are created ASCII,
including the scratch pieces of split loops.

indexOf() from the start of a proven-ASCII string searches bytes
directly, and slice() of one skips the UTF-16 index map. The one-byte
case of the byte search reaches memchr without a stack frame.
