7221bd682f Revert "Revert "Expand optimizations regarding short-circuting a bit"" 
This reverts commit 3770a5ac66.
Fixes the bug which probably made make install fail on travis
(It never happened to me that all tests passed, but make install failed...)

d96dda8d49 Fixed Bug #69761 (Serialization of anonymous classes should be prevented) 
And also cleanup anonymous class compiling, it make no sense prefix a
namespace to anonymous class name. and it is always lowcased and
interned string.

7c2a0157c7 Cache the class_name typehint key in arg_info 
This leads to up to 2% improvement on one tested real world application by not having to always recalculate the lowercased string and its hash

402f697068 Remove zend_init_list 
No longer used - zend_add_to_list already covers this.

Also marked zend_add_to_list as static and dropped it from the header.

e13803d15b Inline zend_find_builtin_type 
This function was used only inside of zend_find_builtin_type_by_name,
which is also used only one time.

339283c523 Rename some variables and functions 
The way these are used have little to do with them being scalars;
they are just tuples with names, lengths and IS_* constants. We
will probably reuse these in the future with other types.

7a88d16cf3 Use ZEND_JMP instead of ZEND_BRK/ZEND_CONT 
Emit necessary FREEs during compilation, convert to JMP during
pass_two (we may not know target opline beforehand).

9325ada725 Embed break/continue depth into opline 
Previously a separate lval literal was used - this is probably a
leftover from the time where the break level could still be
specified dynamically.

3cbe3903fa Move loop var stack management into begin/end loop 
Also set start to -1 in begin_loop already, so the info that a
loop variable is not used is already available at compile-time.

Nikita Popov
d0e265392f Drop FREE_ON_RETURN flag, check brk_cont->start instead 
Start >= 0 already tells us whether or not the loop has a loop
variable, no need to add extra flags to opcodes.

Also added a test for a case where FREE_ON_RETURN is relevant,
we didn't seem to have any coverage for this.

3dba00bc31 Fix scope_is_known() for class constants 
Here the active_op_array is still the surrounding file, but we
do know the scope.

6ef8ae65a2 Allow self etc in eval / file scope 
This fixes a regression from 16a9bc1ec2.
Together with the recent closure related changes this should allow
all usages of self etc, while previously (in PHP 5) some things like
self::class did not work.

ab97606b8a Fix compiler assumptions about self/etc wrt closures 
* Don't throw an error if self/parent/static are used in a closure
  (outside a class).
* Don't propagate self:: constants into closures
* Use runtime fetch for self::class in closures

Fixes bug #66811.

dd1fdfb17c Use ZEND_FETCH_CLASS_NAME for dynamic self::class etc 
Extend the opcode to support getting the parent and static name and
then use it for dynamic ::class resolution.

110759386e ext tokenizer port + cleanup unused lexer states 
we basically added a mechanism to store the token stream during parsing
and exposed the entire parser stack on the tokenizer extension through
an opt in flag: token_get_all($src, TOKEN_PARSE).

this change allows easy future language enhancements regarding context
aware parsing & scanning without further maintance on the tokenizer
extension while solves known inconsistencies "parseless" tokenizer
extension has when it handles `__halt_compiler()` presence.

16a9bc1ec2 Disallow self etc outside classes at compile-time 
Also fix a bug with return types where "self" was rejected inside
a class, but not on a method.

Fallout: A couple of tests changed to more generic error messages.
