perf: make performance great again

[Chronostasys]

This is a massive performance update.

With this update, the ray trace program is about 20x faster than before, we even beat the golang implementation on my computer (MacBook Pro M2 13-inch 16GB).

Main changes:

• Update our escape pass so that it can find more stack allocable variables, reduce GC pressure. It now can rewrite function's arguments from heap pointers to stack pointers.
• Update our optimize pipeline (mainly O3 pipeline), the new pipeline will run escape pass a few times combined with other passes.
• Rewrite GC C api interfaces, thus we can use llvm's native thread local implementation, which is proved to reduce a lot of overhead comparing to Rust's thread local.
• Reimplement GC malloc hot path in llvm ir, so that most heap allocation won't have ffi overhead, and the hot path itself can be optimize by LLVM.
• Rewrite some of GC logic to achieve better performance.

Bugfixes:

• Fixed a bug in match statement which may cause it treat every type as generic type.
• Fixed wrong ir code was generated in the new if let ... impl ... statement if the type isn't satisfy the condition.
• Fixed some trait implemented methods may have wrong scope modifier.
• Fixed a bug causing GC stuck thread wait for more 100ms before reaching safepoint.

TODOS:

• The JIT & REPL does not support native thread local, so this commit actually break them. Need to find a way to walk around.
• The heap alloc hot path still have some room for optimization.
• We can use chase_lev to make GC mark load of each thread more balance.
