This causes an assertion failure when compiling core with nr2.0, but should
probably be improved. I'm not sure how this code enables built-in derive

Inside a BLOCK node, all of the variables of the scope/block
are chained together and that connects them to the block.
This just adds a comment to that effect as reading the code
it is not so obvious why they need to be chained together.

This moves is_floating_point over to using FLOAT_TYPE_P instead
of manually checking. Note before it would return true for all
COMPLEX_TYPE but complex types' inner type could be integral.
Also fixes up the comment to be in more of the GNU style.

This was a small fix to sort out the segfault to check for nullptr on the
TypePath cases for query type. But when this happened opened up a few bugs
that were hidden under the carpet namely: compile/issue-2905-{1,2}.rs which
has a recursive type query which needs to ne handled but now and error
message is being output for the type path. This happens because we start
resolving a generic struct:
struct Wierd<T>(A<(T,)>);
So the child field A is also generic and the generic argument of the tuple
of T needs to be applied to this generic field. This causes a chunk of
code to do bounds checking to ensure the bounds are ok, this is also
something that probably might change as generic types will have the bounds
secified anyway but thats besides the case right now. So once this bounds
checking occurs we endup looking at the impl block for Wierd<i32> which is
also grand but we still havent finished resolving the parent type of Wierd
which is recusive. But the query type system needs to check for that.
The other issue was: compile/issue-3022.rs which is a resolution issue:
impl<T: Foo<U>, U> Foo<U> for Bar<T, U>
The bound of Foo<T> is added to T before U is resolved but this was hidden
before the new error message was added. So now we have a generic
arguements handler being used correctly all over the code base apart from
1 last case for Traits but we will deal with that later. This handles the
case by setting up the type parameters upfront then sorting out their
bounds.

We need to setup the main_identifier_node for MAIN_DECL_P checks in the
middle-end. But it is valid to have a main function/method on impl blocks.
So we need to flag if this is a "root" item or not, which is one that is
jsut an HIR::Function on part of the Crate::items as oppposed to a
HIR::Function which is part of an HIR::ImplBlock as part of the HIR::Crate.
Some small cleanups have been added here too.

Const decls are just delcarations wrapping the value into the DECL_INITIAL
and the shift checks we have assume no decls are involved and its just flat
values. This patch simply unwraps the constant values if they exist.
Fixes Rust-GCC#3665
gcc/rust/ChangeLog:
* rust-gcc.cc (arithmetic_or_logical_expression): unwrap const decls
gcc/testsuite/ChangeLog:
* rust/compile/issue-3665.rs: New test.

When we resolve paths we resolve to Types first we walk each segment to
the last module which has no type but then in the event that the child
of a module is not found we have a null root_tyty which needs to be caught
and turned into an ErrorType node.
Fixes Rust-GCC#3613
gcc/rust/ChangeLog:
* typecheck/rust-hir-type-check-type.cc (TypeCheckType::resolve_root_path):
catch nullptr root_tyty
