From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Optimize isInWorldBounds and getBlockState for inlining
Hot methods, so reduce # of instructions for the method.
Move is valid location test to the BlockPosition class so that it can access local variables.
Replace all calls to the new place to the unnecessary forward.
Optimize getType and getBlockData to manually inline and optimize the calls
