mach_vm_remap() allows to create a dual mapping without having to use a file descriptor, which has to open a file or shm memory. The problem is that the recent macos version started displaying a popup message when such file is opened and that annoyed a lot of users. Thus, the initial code-path is no longer used, and mach_vm_remap() is used instead. This change only applies for x86 macs. Apple silicon doesn't allow dual mapping and instead uses MAP_JIT.

Breaking Changes
Breaking the API is sometimes inevitable, what to do?
- See Breaking Changes Guide, which is now part of AsmJit documentation
- See asmjit tests, they always compile and provide implementation of many use-cases:
- asmjit_test_emitters.cpp - Tests that demonstrate the purpose of emitters
- asmjit_test_assembler_x86.cpp - Tests targeting AsmJit's Assembler (x86/x64)
- asmjit_test_compiler_x86.cpp - Tests targeting AsmJit's Compiler (x86/x64)
- asmjit_test_instinfo.cpp - Tests that query instruction information
- asmjit_test_x86_sections.cpp - Multiple sections test.
