Subject: [PATCH 6/8] ac: add reusable helpers for direct LLVM compilation
5+
6+
This is basically LLVMTargetMachineEmitToMemoryBuffer inlined and reworked.
7+
8+
struct ac_compiler_passes (opaque type) contains the main pass manager.
9+
10+
ac_create_llvm_passes -- the result can go to thread local storage
11+
ac_destroy_llvm_passes -- can be called by a destructor in TLS
12+
ac_compile_module_to_binary -- from LLVMModuleRef to ac_shader_binary
13+
14+
The motivation is to do the expensive call addPassesToEmitFile once
15+
per context or thread.
