eff72eeffa Fix #718: PrettyPrinter breaks nested ternaries 
Mark ternary as non-associative operator, as left-associative use
is deprecated in PHP 7.4 and removed in PHP 8.0.

[PHP 8.0] Add attributes support (#661) 
Adds support for PHP 8 attributes, represented using `AttrGroup` nodes
containing `Attribute` nodes. The `attrGroup` subnode is added to all
nodes that can have attributes.

This is still missing FPPP support.

f66a32e2df Emulate PHP 8 attribute syntax 
Perform emulation by replacing #[ with %[, then patching % back
to # and coalescing #[ into T_ATTRIBUTE if it is a freestanding
token.

39b046007d Refactor token emulator registration 
Only determine needed emulators based on PHP version once, and
add an adaptor that allows treating forward and reverse emulation
the same.

Previously the isEmulationNeeded() check was too conservative,
as it also considered emulators that are not relevant for the
version. Though possibly that check should just be dropped
altogether.

9dda080a9d Allow expressions in isset() 
Partial fix for #653. PHP 7 allows expressions inside isset(), but

isset(($x)) is allowed, though this is not intentional.

a2443aaefa Make check in numeric literal separator emulator more precise 
a) Don't check for !== false, preg_match() return 0 if there is
no match. This effectively means that the check was always true.
b) Check for hex characters only if there's an 0x prefix. 1_1 is
very likely a numeric separator, but a_b might well be part of
an identifier.

Fixes #639.

60d025a914 Fix attributes for zero-length nop nodes 
Previously zero-length nop nodes used the lookahead start attributes
and current end attributes. This choice ends up being somewhat weird,
because the end attributes will be the at the last non-whitespace,
non-comment token, which might be quite far back. More problematically,
we may not have encountered any non-discarded token if we're at the
start of the file, in which case we will have no end attributes to
assign.

Change things to use a canonical "zero-length" node representation,
where the end position (token & file) will be exactly one before the
start position.

Fixes #589.
