* refactor: move EOF check into yp_unescape_calculate_difference
parser_lex is a bit more readable when we can rely on that behavior
* fix: octal and hex digits at the end of a file
Previously this resulted in invalid memory access.
* fix: unicode strings at the end of a file
Previously this resulted in invalid memory access.
* Unterminated curly-bracket unicode is a syntax error

Also, a similar test and fix for interpolated regular expressions.
This snippet:
<<-A.g//,
A
/{/, ''\
previously created a regular expression node with inverted start and
end:
RegularExpressionNode(14...13)((14...15), (15...21), (12...13), ", ''", 0),
which failed an assertion during serialization.
After this change:
RegularExpressionNode(12...15)((14...15), (15...21), (12...13), ", ''", 0),
Found by the fuzzer.

The snippet added in this commit previously resulted in a CallNode
with inverted start and end locations:
> AssocNode(15...13)(
> CallNode(15...13)(
StringNode(15...17)((15...16), (16...16), (16...17), ""),
nil,
(12...13),
nil,
ArgumentsNode(12...13)([MissingNode(12...13)()]),
nil,
nil,
0,
"/"
),
MissingNode(13...13)(),
(13...13)
),
which failed an assertion during serialization.
After this change, it looks better:
> AssocNode(12...13)(
> CallNode(12...17)(
StringNode(15...17)((15...16), (16...16), (16...17), ""),
nil,
(12...13),
nil,
ArgumentsNode(12...13)([MissingNode(12...13)()]),
nil,
nil,
0,
"/"
),
MissingNode(13...13)(),
(13...13)
),
Found by the fuzzer.

The presence of the heredocs in this snippet with invalid syntax:
for <<A + <<B
A
B
causes the MissingNode to have a location after other nodes in the
list, resulting in a StatementsNode with inverted start and end
locations:
[ForNode(0...14)(
MultiWriteNode(4...7)([InterpolatedStringNode(4...7)((4...7), [], (14...16))], nil, nil, nil, nil),
MissingNode(16...16)(),
> StatementsNode(16...14)(
[MissingNode(16...16)(), InterpolatedStringNode(10...13)((10...13), [], (16...18)), MissingNode(13...14)()]
),
(0...3),
(16...16),
nil,
(14...14)
)]
which failed an assertion during serialization.
With this fix, the node's locations are:
[ForNode(0...14)(
MultiWriteNode(4...7)([InterpolatedStringNode(4...7)((4...7), [], (14...16))], nil, nil, nil, nil),
MissingNode(16...16)(),
> StatementsNode(10...16)(
[MissingNode(16...16)(), InterpolatedStringNode(10...13)((10...13), [], (16...18)), MissingNode(13...14)()]
),
(0...3),
(16...16),
nil,
(14...14)
)]

Previously this resulted in invalid memory access as well as a
cascading failed assertion:
src/enc/yp_unicode.c:2224: yp_utf_8_codepoint: Assertion `n >= 1' failed.
Found by the fuzzer.
