cleanup TSRMLS_FETCH

Avoid double IS_INTERNED() check

Split big _zend_handle_numeric_str() into small always inlined function that makes initial check and regular big function

optimized colision list traverse

Remove HASH_NEXT_INSERT flag

We already pass ht->nNextFreeElement and the rest is handled by
ZEND_HASH_ADD.

Remove two more always-true conditions

Optimized FE_RESET and FE_FETCH

Remove always-true comparisons

Update types in zend_hash

* String lengths are size_t
* Indexes are uint32_t
* Flags are uint32_t
* Booleans are zend_bool

Split and optimize loop

further fixes to ext/standard and zend

first shot on merging the core fro the int64 branch

Fixed conversion of empty packed array into hash

Use reference counting instead of zval duplication

Introduced immutable arrays. They don't need to be copyed and may be used directly from SHM.

Use specialized functions instead of macros

Removed useless initializations

Use optimized zend_array_dup() function. convert zend_hash_num_elements() and zend_hash_next_free_element() into macros.

Removed the old hack that was originally developed to support constants in array indeces, and isn't needed anymore after the Bob's patch.

Use new hash iteration API and avoid old zend_hash_update_current_key() hack

Convert to unpacked before deleting elements

Return FAILURE immediately if a string index removal is attempted.

Moved condition higher up
