When setting an array index which is beyond the end of the last currently
preallocated chunk and not evenly divisible by the chunk size, the array
entries list was not properly reallocated, resulting in invalid memory
writes.

When compiling certain expressions as first statement of an ucode
program, e.g. a while loop in raw mode, a jump instruction to offset
zero is emitted which was incorrectly treated as placeholder by the
compiler.

Skip interpreter lines in any source buffer and handle the skipping in the
lexer itself, to avoid reporting wrongly shifted token offsets to the
compiler, resulting in wrong error locations and source contexts.

In a loop statement like `for (let x = 1, y = 2; ...)` the initialization
statement was incorrectly interpreted as `let x = 1; y = 2` instead of the
correct `let ..., y = 2`, triggering reference error exceptions in strict
mode.
Solve the issue by continue parsing the rest of the comma expression
seqence as declaration list expression when the initializer is compiled
in local mode.

Due to the special code path parsing the leading label portion of a
parenthesized expression, slashes following a label were improperly
treated as regular expression literal delimitters, emitting a syntax
error when an otherwise valid expression such as `a / 1` was being
parsed as first sub expression of a parenthesized expression.

When emitting byte code for break or continue statements, ensure that local
variables in all containing scopes up to the loop body scope are popped,
not just those in the same scope the statement is located in.

Due to the special code path parsing the leading label portion of a
parenthesized expression, keywords following a property access operator
(TK_DOT, `.`) weren't properly handled, emitting a syntax error when an
otherwise valid expression such as `value.default` was being parsed as
first sub expression of a parenthesized expression.

- Ensure that split by string produces an initial empty string in the
result array when the string to split starts with the split substring
- Ensure that split by string produces a trailing empty string in the
result array when the string to split ends with the split substring
