JIT Refactoring:

- Move duplicate system independent functions from zend_jit_x86.dasc and
  zend_jit_arm64.dasc into zend_jit.c
  * zend_jit_is_constant_cmp_long_long()
  * zend_jit_needs_call_chain()
  * skip_valid_arguments()
  * zend_ssa_cv_info()
  * zend_jit_may_avoid_refcounting()
  * zend_get_known_property_info()
  * zend_may_be_dynamic_property()
- Move common definitions from zend_jit_x86.dasc and
  zend_jit_arm64.dasc into zend_jit.c
  * GCC_GLOBAL_REGS
  * PROFITABILITY_CHECKS
  * BP_JIT_IS
  * sp_adj_kind
  * sp_adj[]
- Remove unused DynAsm macros
  * ADDR_CMP (arm64)
- Inline and remove DynAsm macros used once
  * LOAD_BASE_ADDR (arm64 and x86)
  * PUSH_BASE_ADDR (x86)
  * MEM_OP3_3 (x86)
  * SET_Z_PTR (x86)
- Rename DynAsm macros
  * MEM_LOAD_OP_STORE -> MEM_UPDATE (arm64)
  * MEM_LOAD_OP_STORE_ZTS - > MEM_UPDATE_ZTS (arm64)
  * ADDR_OP1 -> PUSH_ADDR (x86)
  * ADDR_OP2_2 -> ADDR_STORE and ADDR_CMP (x86)
  * MEM_OP2_1_ZTS -> MEM_STORE_ZTS, MEM_CMP_ZTS, MEM_UPDATE_ZTRS (x86)
  * MEM_OP2_2 -> MEM_LOAD and MEM_LOAD_OP (x86)
  * MEM_OP2_2_ZTS -> MEM_LOAD_ZTS and MEM_LOAD_OP_ZTS (x86)
  * SSE_AVX_OP -> DOUBLE_CMP (x86)
  * SSE_GET_LONG -> DOUBLE_GET_LONG (x86)
  * SSE_GET_ZVAL_LVAL -> DOUBLE_GET_ZVAL_LVAL (x86)
  * SSE_GET_ZVAL_LVAL -> DOUBLE_GET_ZVAL_LVAL (x86)
  * SSE_GET_ZVAL_DVAL -> DOUBLE_GET_ZVAL_DVAL (x86)
  * SSE_SET_ZVAL_DVAL -> DOUBLE_SET_ZVAL_DVAL (x86)
