Adds 2 new AIR instructions: * dbg_var_ptr * dbg_var_val Sema no longer emits dbg_stmt AIR instructions when strip=true. LLVM backend: fixed lowerPtrToVoid when calling ptrAlignment on the element type is problematic. LLVM backend: fixed alloca instructions improperly getting debug location annotated, causing chaotic debug info behavior. zig_llvm.cpp: fixed incorrect bindings for a function that should use unsigned integers for line and column. A bunch of C test cases regressed because the new dbg_var AIR instructions caused their operands to be alive, exposing latent bugs. Mostly it's just a problem that the C backend lowers mutable and const slices to the same C type, so we need to represent that in the C backend instead of printing two duplicate typedefs.
