Bring static scalar arrays in line

Bring static scalar AST more in line with normal AST

Const eval unary pm (as previously)

Fixed bug #67368 (Memory leak with immediately dereferenced array in class constant)

Implement constant expression folding as a separate pass

zend_ast_dynamic_ast returns new node

AST stage 2.4

Add ability to specify additional attr in AST

Make ast->children a uint

Future optimization: only use uint for dynamic lists and use a
uchar or even an introspection function to get the child count.

AST-based compiler: Stage 1

Remove (&ast->u.child)[i] weirdness

Re-applyed Bob's patch with minor fixes

Reverted Bob's patch (it breaks many tests when run with opcache and needs to be fixed first).

Fix ZTS build

Re-added fix for bug #66015 and adapted for phpng branch

Optimized constant lookup

Fixed tests for recent constant array changes

Removed useless void* parameter and replaced with zend_bool on zval_update_constant* functions

Fixed disallowal of array usage in constants at run-time
Added at the same time the possibility of array dereferencing
to complete the set of features (useful application of arrays in constan

Fix bug #66015 by reverting "Removed operations on constant arrays."

Constant duplication optimization
Argument receiving optimization

Refactored ZVAL flags usage to simplify various checks (e.g. Z_REFCOUNTED(), candidate for GC, etc)

Allow T_POW in constant expressions

Use better data structures (incomplete)
