`zend_uchar` suggests that the value is an ASCII character, but here,
it's about very small integers. This is misleading, so let's use a
C99 integer instead.
On all architectures currently supported by PHP, `zend_uchar` and
`uint8_t` are identical. This change is only about code readability.
* Use arena in DCE instead of multiple alloca()
This requires passing the optimizer context
* Use our do_alloca() instead of alloca()
* Use emalloc in DEBUG builds instead of stack allocations for do_alloca()
This helps detecting that we correctly free do_alloca()
Pass1 handles a number of special functions that can be evaluated
under some circumstances. Move the core logic into a separate
helper, as I believe that SCCP should reuse this.
This handles references to the current class through its name
rather than self (and for cases where is is not linked yet and
thus not covered by the context lookup). Rather than handling this
only for FETCH_CLASS_CONSTANT optimization, integrate this into
the generic get_class_entry() utility.
This code is repeated a few time. Two occurrences additionally
contained checks for user classes in CG(class_table) with the
same file name, but as far as I know these should always be in
the script class_table, so I'm omitting the check here.
1. Update: http://www.php.net/license/3_01.txt to https, as there is anyway server header "Location:" to https.
2. Update few license 3.0 to 3.01 as 3.0 states "php 5.1.1, 4.1.1, and earlier".
3. In some license comments is "at through the world-wide-web" while most is without "at", so deleted.

Closes GH-6822.
This only moves the files, adjusts the build system, exports APIs
and does minor fixups to make sure the code builds.
This does not yet try to make the optimizer usable independently
of opcache.
Closes GH-6642.
