Christoph M. Becker ef77d3c89f Fix #81206: Multiple PHP processes crash with JIT enabled

case with JIT, but I ran into a case that does trigger with JIT
once we have typed properties.

Nikita Popov d550c8488a Fix unbalanced NEW call_level in JIT 
For NEW followed by DO_FCALL, we handle both together and skip
over the DO_FCALL, which means that the call_level for it will
not be decremented. Do so explicitly instead.

Nikita Popov 0e932f7cea Don't directly include zend_jit_gdb.c 
Compile the file separately and only include a header. There doesn't
seem to be a good reason to directly include the C file here, and
this ensures that there are no symbol clashes (see GH-7197).

Hao Sun 3e164dee99 JIT/AArch64: Support shifted immediate (#7165) 
* JIT/AArch64: Support shifted immediate

As pointed out by MikePall in [1], shifted immediate value is supported.
See [2]. For example, `add x0, x1, #4096` would be encoded by DynASM
into `add x0, x1, #1, lsl #12` directly.

In this patch, a helper is added to check whether an immediate value is
in the two allowed ranges: (1) 0 to 4095, and (2) LSL #12 on all the
values from the first range.

Note that this helper works for add/adds/sub/subs/cmp/cmn instructions.

Change-Id: I4870048b9b8e6c429b73a4803af2a3b2d5ec0fbb

* Deprecatd CMP_IMM/ADD_SUB_IMM and add test cases

Macros CMP_IMM and ADD_SUB_IMM are deprecated and instead we use
this helper to guard the immediate encoding.

Add two 64-bit only test cases, since 64-bit integers are used
and tested inside.
