While JMPZNZ can avoid execution of a separate JMP opcode in some
cases, it also prevents smart branch optimization, so creating
JMPZNZ may actually have a negative effect. It also adds additional
complexity for optimizations.
Drop JMPZNZ in favor of JMPZ+JMP or JMPNZ+JMP.
Closes GH-7857.
This is already skipped for TMP/VAR, but also needs to be skipped
for CV, because we need to insert CHECK_VAR in that case, if we're
being pedantic. That leaves us with CONST as the only case
we can handle, which is already covered by constant folding.
This optimization never actually triggers in our tests, so it's
not a big loss.
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.

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.
