Port jit to Rust The following files and functions were ported: - jit.c - codegen.c - _jit functions in instructions.c and misc_instr.c - generate_{analyzer,jit}.js (produces Rust code) - jit_ from cpu.c And the following data structures: - hot_code_addresses - wasm_table_index_free_list - entry_points - jit_cache_array - page_first_jit_cache_entry Other miscellaneous changes: - Page is an abstract type - Addresses, locals and bitflags are unsigned - Make the number of entry points a growable type - Avoid use of global state wherever possible - Delete string packing - Make CachedStateFlags abstract - Make AnalysisType product type - Make BasicBlockType product type - Restore opcode assertion - Set opt-level=2 in debug mode (for test performance) - Delete JIT_ALWAYS instrumentation (now possible via api) - Refactor generate_analyzer.js - Refactor generate_jit.js 2018-07-03 17:28:33 +02:00			`pub const PREFIX_REPZ: u32 = 0b01000;`
