Moving the zend_iterator_dtor from dual_it_dtor to dual_it_free_storage
exposed this GC leak in an existing test. Forward the result of the
iterator get_gc to the dual_it get_gc.
When doing a non finishing flush, BZ2_bzCompress() returns BZ_FLUSH_OK
(not BZ_FINISH_OK) what requires us to do further flushes right away.
We also refactor the while-loop as do-loop.
Closes GH-7113.
When the memory limit is restored during shutdown, we may still
be using a lot of memory. Ignore the failure at that point and
set it again after the MM is shut down, at which point memory
usage should be at its lowest point.
MSVC doesn't support __attribute__((unused)), so this can cause
a lot of warnings for extensions. Use the (void) trick instead.
However, this requires us to initialize the variable as well,
to ensure that ubsan does not read a trap representation.
Updates the deprecation message for implicit incompatible float to int conversion from:
```
Implicit conversion from non-compatible float %.*H to int in %s on line %d
```
to
```
Implicit conversion from float %.*H to int loses precision in %s on line %d
```

This macro is a footgun because it creates an uninitialized array
(only an allocation). This macro is no longer used in php-src,
and we have better alternatives like array_init() or
ZVAL_ARR(arr, zend_new_array(size_hint)).
One shift instruction can be saved if 'shifted register' is used.
It's worth noting that the destination register of previous shift
instruction doesn't hold the shift result any longer now. And we have to
guarantee that 'shifted register' mode is applied to all the use sites
of this destination register.
Besides, several code-style issues are fixed.

The way to fix it is to disable certain match start optimizaions. The
observed performance impact appears negligible ATM, compared to the
functional regression revealed.
A possible side effect might occur if a pattern uses (*COMMIT) or
(*MARK), which is however not a very broadly used syntax in PHP. Still
this should be observed and handled by possibly adding a possibility to
reverse PCRE2_NO_START_OPTIMIZE on the user side.
One test shows a behavior change, where instead of int 0 the match
would produce an error and return false. Except strict comparison
is used, this should be acceptable.

Allows flags besides ZEND_FIBER_FLAG_THREW to be set without causing this method to throw.
The method will not be called after a bailout, so the ZEND_FIBER_FLAG_BAILOUT case was removed.
The following warning message would be produced for macOS on Apple
silicon.

Flag -Wincompatible-pointer-types is enabled by default in Clang [1],
but not in GCC [2].
Adding explicit type conversion would remove this warning.

- perform constant shift by single instruction
TODO: DynAsm: can't encode "lsl x0, x0, #var" !!!
- avoid usage of REG1 for variable shift (it was x86 limitation)
- enable register reuse for SL/SR instructions
- remove special scratch register handling for SL/SR (it was x86
limitation)
- Remove need for extra scratch registers. AArch64 JIT backend
don't use extra register for constants. It uses reserved TMP
registers.
This test case did 100,000 includes of a non existing file to show the
memory leak; this is not necessary, because after the first failing
include, memory is not supposed to increase for further includes.
Closes GH-7088.
Currently interface methods with visibility `private` or `protected` fail
with an error message:
Access type for interface method A::b() must be omitted
However, explicitly setting visibility `public` is allowed and often desired.
This commit updates the error message to:
Access type for interface method A::b() must be public
* JIT/AArch64: Code refactoring for macros
Update the comments and rename arguments for some macros.
The following macros are renamed:
SAFE_MEM_ACC_WITH_UOFFSET -> MEM_ACC_64_WITH_UOFFSET
SAFE_MEM_ACC_WITH_UOFFSET_32 -> MEM_ACC_32_WITH_UOFFSET
SAFE_MEM_ACC_WITH_UOFFSET_BYTE -> MEM_ACC_8_WITH_UOFFSET
MEM_STORE_BYTE_ZTS -> MEM_STORE_8_ZTS
MEM_STORE_ZTS -> MEM_STORE_64_ZTS
MEM_LOAD_ZTS -> MEM_LOAD_64_ZTS
MEM_LOAD_BYTE_ZTS -> MEM_LOAD_8_ZTS
ADD_IP_FROM_CST -> ADD_IP_WITH_CONST
The following macros are deprecated and removed:
SET_Z_PTR, GET_Z_W2, SET_Z_W2

* Use MEM_ACCESS_*_WITH_UOFFSET
It's more accurate to use "MEM_ACCESS_*_WITH_UOFFSET" than
"MEM_ACC_*_WITH_UOFFSET".
Change-Id: I71479a809008848b61c4786016e6c10110e6aa8b
* Revert the updates for macros ADD_IP_WITH_CONST and LONG_ADD_SUB_WITH_IMM
As pointed by Dmitry, (int32_t) (1LL << 32) would make the assertion
"TRUE", which is not expected by us.
