erts: Add debug assertions for match state sanity
hipe: Add test for matching of writable binary

Seen symptom: Hipe compiled code with <<C/utf8, ...>> = Bin does sometimes
not match even though Bin contains a valid utf8 character. There might be
other possible binary matching symptoms, as the problem is not utf8
specific.
Problem: A writable binary was not "emasculated" when the matching started
(as it should) by the hipe compiled code.
Fix: Add a new primop emasculate_binary(Bin) that is called when
a matchstate is created.
ToDo: There are probably room for optimization. For example only call
emasculate_binary if ProcBin.flags is set.

The hipe_bifs:make_native_stub/2 and hipe_bifs:get_emu_address/1
BIFs were originally used by hipe_unified_loader.erl, but the
code been obsolete and disabled for ages.
Remove the BIFs and all references to them.
In hipe_unified_loader.erl, remove the no-op emu_make_stubs/1
function.

This commit is a preparation for eliminating a race condition
loading the native code for modules whose BEAM code has already
been loaded. Here we introduce two new BIFs so that looking up
a fun entry is separate from setting the native address in the
fun entry.
