Allow all types of callee's to be tail called. But avoid automatic tailcall if the callee is a result of bitcast to avoid losing necessary zext / sext etc.

live until dwarf emission and other random stuff that is
not yet going through MCStreamer is upgraded.  It only

ByVal frame object size should be that of the byval argument, not the size of the type which is just a pointer. This is not known to break stuff but is wrong nevertheless.

It's unclear if the matcher is nondeterminstic of what here,
but I'm getting matches without TAILCALL and some other hosts
are getting matches with it.

Now the only use of the ELF writer is the JIT, which won't be
easy to fix in the short term. :( :(
