SEND_VAR_NO_REF optimization

initialiize opline for the case it lands in default case

convert_to_string also does the check

A better fix(do the convertion in compile time)

fix warning not all control paths return a value

fix datatype mismatches

and convert APIs to size_t where zend_string internally used

Fixed "instanceof" with undefined classes

Embed FETCH_CLASS <string> into the following NEW

Get rid of ZEND_FETCH_MAKE_REF

Embed FETCH_CLASS <string> into the following INSTANCEOF

Don't use opline->extended_value for FETCH_CLASS flags where it's unnecessary

Optimized ASSIGN_DIM and related opcodes

bring back all the TSRMLS_FETCH() stuff

for better comparability with the mainstream

Ensure __LINE__ is always accurate

Fix unused variable warning

Fixed list() behavior inconsistency (string handling is disabled for all cases, ArrayAccess objects handling is enabled for all cases, ZEND_FETCH_DIM_TMP_VAR opcode is renamed into ZEND_FETCH_LIST, Z

Fixed list() behavior inconsistency (string handling is disabled for all cases, ArrayAccess objects handling is enabled for all cases, ZEND_FETCH_DIM_TMP_VAR opcode is renamed into ZEND_FETCH_LIST, ZEND_FETCH_ADD_LOCK flag is removed).

reworked the patch, less new stuff but worky

TLS is already used in TSRM, the way exporting the tsrm cache through
a thread local variable is not portable. Additionally, the current
patch suffers from bugs which are hard to find, but prevent it to
be worky with apache. What is done here is mainly uses the idea
from the RFC patch, but

- __thread variable is removed
- offset math and declarations are removed
- extra macros and definitions are removed

What is done merely is

- use an inline function to access the tsrm cache. The function uses
the portable tsrm_tls_get macro which is cheap
- all the TSRM_* macros are set to placebo. Thus this opens the way
remove them later

Except that, the logic is old. TSRMLS_FETCH will have to be done once
per thread, then tsrm_get_ls_cache() can be used. Things seeming to be
worky are cli, cli server and apache. I also tried to enable bz2
shared and it has worked out of the box. The change is yet minimal
diffing to the current master bus is a worky start, IMHO. Though will
have to recheck the other previously done SAPIs - embed and cgi.

The offsets can be added to the tsrm_resource_type struct, then
it'll not be needed to declare them in the userspace. Even the
"done" member type can be changed to int16 or smaller, then adding
the offset as int16 will not change the struct size. As well on the
todo might be removing the hashed storage, thread_id != thread_id and
linked list logic in favour of the explicit TLS operations.

Move list() condition into assign_znode

The condition in compile_foreach was using ->attr instead of ->kind
and as such never passed. It only worked because assign_znode already
supported this case by indirecting via zend_compile_assign. Now it
implements it with a direct call.
