rPHU4b75e0c34e52: Add coalesce and spaceship operators to xhpast

Summary

$value ?? $other is roughtly translates to isset($value) ? $value : $other
$a <=> $b translates to ($a < $b) ? -1 : (($a > $b) ? 1 : 0).

Because these new tokens appear in-between other tokens, a lot of token values were updated. All test cases have been updated to have the correct token values.

Test Plan

Fully rebuild xhpast, run all parser tests.

On a sidenote, arc unit --everything in arcanist seems totally okay with these changes as well.

src/parser/xhpast/parser_tokens.php
5	I copied / adapted this list from `YYTOKENTYPE` in `parser.yacc.cpp`. It seemed a bit out-of date.

Remove useless %token declaration for T_COALESCE

This is starting to bite us now - especially the coalesce construct is so useful that people started using it, taking lint syntax errors for granted.

If there's anything in particular I can change here to make reviewing it more bearable please let me know.

I vaguely imagined fixing the unit test format to be human-readable while you were away for the weekend, but obviously did not.

This revision is now accepted and ready to land.May 18 2016, 4:58 PM
