In PHP static properties are shared between inheriting classes,
unless they are explicitly overwritten. However, because this
functionality was implemented using reference, it was possible
to break the implementation by reassigning the static property
reference.
This is fixed by switching the implementation from using references
to using INDIRECTs, which cannot be affected by userland code.
The sole purpose of `PHPDBG_FILE`, `PHPDBG_METHOD`, `PHPDBG_LINENO` and
`PHPDBG_FUNC` has been to be passed as first argument to `phpdbg_break`.
However, this functions is replaced as of PHP 5.6.3 by
`phpdbg_break_file`, `phpdbg_break_method` and 'phpdbg_break_func`,
respectively. Therefore, we're finally removing the useless constants.
This fixes the behavior when the storage location of the fetch is
modified before the operand is dereferenced by the using VM opcode.
Furthermore it elimiates references as a possible return value from
*_R opcodes, which will give us more opportunities for inferences,
in particular in regard to typed properties.
If a locale other than C is active, character tables are saved into the
compile context. Every compiled pattern will have a pointer to the
character table, that was present in the context at the time of the
pattern compilation. Thus, the cache entries don't need to carry char
tables pointer, which reduces their size to 8 bytes on 64-bit. Instead,
the generated character tables are tracked in a separate HashTable. If a
character table was generated before, it'll be assigned to the compile
context when the locale changes. Otherwise a new char table will be
generated and cached.
