Thus far the LoadElimination didn't consider CheckHeapObject a renaming operation and would therefore miss opportunities to eliminate redundant loads or map checks where the input is not checked for sminess in all cases. This kind of pattern is very common with code that results from builtin inlining in JSCallReducer, as here we don't unconditionally insert CheckHeapObject nodes if we can tell from the graph that the receiver already has a certain map (by walking the effect chain upwards).

This fixes several issues related to off-heap trampoline handling on ia32. Unlike other architectures, ia32 uses a pc-relative call/jump for the off-heap trampoline. That means we cannot skip reloc info emission, and we need to relocate when the buffer grows during code generation. Finally, inlined trampolines must not clobber and thus also need to use a pc-relative call/jump. Drive-by: Use PreserveRootIA32 config only for whitelisted builtins to build successfully by default.
