After the previous commit, we no longer access Walkdef on anything but
ir.Names, so we can remove them from the Node interface and miniNode.
The flag bits storage should also move from miniNode.bits to
Name.flags, but the latter is already full at the moment. Leaving as a
TODO for now.

To do closure conversion during escape analysis, we need to walk the
AST in order. So this CL makes a few changes:
1. Function literals are walked where they appear in their enclosing
function, rather than as independent functions.
2. Walking "range" and "switch" statements is reordered to visit the
X/Tag expression up front, before the body.
3. Most assignments are refactored to use a new assignList helper,
which handles 1:1, 2:1, and N:N assignments. N:1 function call
assignments are still handled directly by the OAS2FUNC case.
4. A latent missed-optimization in escape.addr is fixed: the
ONAMEOFFSET case was failing to update k with the result of calling
e.addr(n.Name_). In partice, this probably wasn't an issue because
ONAMEOFFSET is likely only used for PEXTERN variables (which are
treated as heap memory anyway) or code generated by walk (which has
already gone through escape analysis).
5. Finally, don't replace k with discardHole at the end of
escape.addr. This is already handled at the start of escape.expr, and
we'll want to be able to access the hole's location after escape.expr
returns.

This CL separates out PtrInit and SetInit into a new InitNode
extension interface, and adds a new TakeInit helper function for
taking and clearing the Init list (if any) from a Node.
This allows removing miniNode.SetInit and miniNode.PtrInit, which in
turn allow getting rid of immutableEmptyNodes, and will allow
simplification of the Nodes API.
It would be nice to get rid of the default Init method too, but
there's way more code that expects to be able to call that at the

When deciding whether a captured variable can be passed by value, the
compiler is sensitive to the order that the OCLOSURE node is
typechecked relative to the order that the variable is passed to
"checkassign". Today, for an assignment like:
q, g = 2, func() int { return q }
we get this right because we always typecheck the full RHS expression
list before calling checkassign on any LHS expression.
But I nearly made a change that would interleave this ordering,
causing us to call checkassign on q before typechecking the function
literal. And alarmingly, there weren't any tests that caught this.
So this commit adds one.

In a future CL, I plan to change escape analysis to walk function
literal bodies at the point they appear within the AST, rather than
separately as their own standalone function declaration. This means
escape analysis's AST-walking code will become reentrant.
To make this easier to get right, this CL splits escape analysis's
state into two separate types: one that holds all of the state shared
across the entire batch, and another that holds only the state that's
used within initFunc and walkFunc.
Incidentally, this CL reveals that a bunch of logopt code was using
e.curfn outside of the AST-walking code paths where it's actually set,
so it was always nil. That code is in need of refactoring anyway, so
I'll come back and figure out the correct values to pass later when I
address that.

Closures have their own ONAMEs for captured variables, which their
function bodies refer to. So during inlining, we need to account for
this and ensure the references still work.
The previous inlining handled this by actually declaring the variables
and then either copying the original value or creating a pointer to
them, as appropriate for variables captured by value or by reference.
But this is needlessly complicated. When inlining the function body,
we need to rewrite all variable references anyway. We can just detect
closure variables and change them to directly point to the enclosing
function's version of this variable. No need for copying or further
indirection.
Does not pass toolstash -cmp. Presumably because we're able to
generate better code in some circumstances.

One catch is that we only want to report unused-variable errors for

currently. As an approximate solution, we simply check if we've

After using the IR visitor code for a bit, it seems clear that a
simple boolean result type is adequate for tree traversals. This CL
updates ir.DoChildren to use the same calling convention as ir.Any,
and updates mknode.go to generate code accordingly.
There were only two places where the error-based DoChildren API was
used within the compiler:
1. Within typechecking, marking statements that contain "break". This
code never returns errors anyway, so it's trivially updated to return
false instead.
2. Within inlining, the "hairy visitor" actually does make use of
returning errors. However, it threads through a reference to the
hairyVisitor anyway, where it would be trivial to store any needed
information instead. For the purpose of this CL, we provide
"errChildren" and "errList" helper functions that provide the previous
error-based semantics on top of the new bool-based API.

This CL computes a second parallel addrtaken bit that we check
against the old way of doing it. A subsequent CL will rip out the
typechecker code and just use the new way.

Two simplifications:
1. Statements (including ODCLFUNC) don't have types, and the
Func.Nname already has a type. There's no need for a second one.
However, there is a lot of code that expects to be able to call
Func.Type, so leave a forwarding method, like with Sym and Linksym.
2. Inline and remove ir.NewFuncNameAt. It doesn't really save any
code, and it's only used a handful of places.
Passes toolstash -cmp.

Thanks to package reorganizing, we can remove types.TypeLinkSym by
simply having its only callers use reflectdata.TypeLinksym directly.
