Date:   Fri Jun 26 01:23:31 2015 +0200

    Use the new 'ZSTR' macros in the rest of the code.

    Does not change anything to the generated code (thanks to compat macros) but cleaner.

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...)

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.

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.

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.
