Refactor LLVM JIT (#1613)
Refactor LLVM JIT for some purposes: - To simplify the source code of JIT compilation - To simplify the JIT modes - To align with LLVM latest changes - To prepare for the Multi-tier JIT compilation, refer to #1302 The changes mainly include: - Remove the MCJIT mode, replace it with ORC JIT eager mode - Remove the LLVM legacy pass manager (only keep the LLVM new pass manager) - Change the lazy mode's LLVM module/function binding: change each function in an individual LLVM module into all functions in a single LLVM module - Upgraded ORC JIT to ORCv2 JIT to enable lazy compilation Refer to #1468
