optabs.[hc] is a bit of a behemoth. It includes basic functions for querying
what a target can do, related tree- and gimple-level query functions,
related rtl-level query functions, and the functions that actually
generate code. Some gimple optimisations therefore need:
#include "insn-config.h"
#include "expmed.h"
#include "dojump.h"
#include "explow.h"
#include "emit-rtl.h"
#include "varasm.h"
#include "stmt.h"
#include "expr.h"
purely to query whether the target has support for a particular operation.
This patch splits optabs up as follows:
- optabs-query.[hc]: IL-independent functions for querying what a target
can do natively.
- optabs-tree.[hc]: tree and gimple query functions (an extension of
optabs-query.[hc]).
- optabs-libfuncs.[hc]: optabs-specific libfuncs (an extension of
libfuncs.h)
- optabs.h: For now includes optabs-query.h and optabs-libfuncs.h.
Only two files outside optabs need to include both optabs.h and
optabs-tree.h: expr.c and function.c. I think that's expected given
that both are related to expand.
It might be good to split optabs.h further, but this is already quite
a big patch.
I changed can_conditionally_move_p from returning an int to returning
a bool and fixed a few formatting glitches. There should be no other
changes to the functions themselves.

When asking for the type of a receive operation, the compiler would
return an error type if the receive operator was being used on an
invalid channel type and the error would be reported in a later pass.
There are several ways that the type checking pass would not see
the original node and fail to issue the error. This patch modifies
receive operations to give an error immediately once it is known that
the channel type is invalid.
