c62dda9507 Strip trailing doc string newline before parsing escape sequences 
If the doc string ends on an escaped \r, it should not get eaten
as the "last newline".

f4ec6a1e53 Rename Scalar\EncapsedStringPart to InterpolatedStringPart 
It is no longer an expression node, which unfortunately does
require a more awkward type for the Encaps node.

0933986293 Make sure Array nodes can not contain null 
Now that destructuring is always represented using List nodes,
make sure that Array nodes can no longer contain null elements,
so well-typed code doesn't have to deal with them unnecessarily.

If an array does contain empty elements, these are now result in
an error and are represented as a ArrayItem with Error value if
error recovery is used.

The implementation is a bit tricky because at the time the Array
node is created, we cannot tell whether it will be used in a
creation or destructuring context. For this reason the error
reporting is delayed parsing has finished.

Closes #876.

dd63ddbc24 Add php-cs-fixer config and reformat 
The formatting in this project has become something of a mess,
because it changed over time. Add a CS fixer config and reformat
to the desired style, which is PSR-12, but with sane brace placement.

d3d1ee470a Fix #738 incorrect start line for traits 
Empty productions are supposed to be assigned the start attributes
of the lookahead token. Currently, this happens by assigning above
the current stack position when the token it read.

This fails in a situation where we first reduce an empty production
higher up in the stack, and then again reduce an empty production
lower in the stack, without consuming the lookahead token in the
meantime.

Fix this by moving the assignment into the reduction phase. We
also need to do this for error productions, which are effectively
empty.

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.
