/**
* Read token with JSX contents.
*
* In addition to detecting jsxTagStart and also regular tokens that might be
* part of an expression, this code detects the start and end of text ranges
* within JSX children. In order to properly count the number of children, we
* distinguish jsxText from jsxEmptyText, which is a text range that simplifies
* to the empty string after JSX whitespace trimming.
*
* It turns out that a JSX text range will simplify to the empty string if and
* only if both of these conditions hold:
* - The range consists entirely of whitespace characters (only counting space,
* tab, \r, and \n).
* - The range has at least one newline.
* This can be proven by analyzing any implementation of whitespace trimming,
* e.g. formatJSXTextLiteral in Sucrase or cleanJSXElementLiteralChild in Babel.
