cmd/compile: add setNodeSeq, and use it in bimport.go
...
Also rewrite bexport.go to use nodeSeqIterate.
The new setNodeSeq is a transitional generic function to set either a
NodeList or a slice to either a NodeList or a slice. This should permit
us to flip fields from *NodeList to []*Node, or Nodes, without changing
other code.
Passes toolstash -cmp.

cmd/compile/internal/gc: export & import function bodies, but don't hook up
...
Function bodies are not yet hooked up because the node structure is not
100% correct. This commit establishes that we can correctly write bodies
out and read them in again.
- export and import all exported inlined function bodies:
(export GO_GCFLAGS="-newexport"; sh all.bash) working
- inlined functions are not yet hooked up (just dropped on the floor)
- improved tracing output and error messages
- make mkbuiltin.go work for both textual and binary export data
so we can run tests with the new format

cmd/compile: make -A and -newexport compatible
...
Packages compiled with -A may reference the builtin "any" type, so it
needs to be included in the list of predeclared types for binary
import/export.
Also, when -A is used, mark all symbols as SymExport instead of
SymPackage in importsym. This parallels the logic in autoexport and
is necessary to prevent a "export/package mismatch" errors in
exportsym during dumpexport's verifyExport pass.

cmd/compile/internal/gc: compact binary export format
...
The binary import/export format is significantly more
compact than the existing textual format. It should
also be faster to read and write (to be measured).
Use -newexport to enable, for instance:
export GO_GCFLAGS=-newexport; make.bash
The compiler can import packages using both the old
and the new format ("mixed mode").
Missing: export info for inlined functions bodies
(performance issue, does not affect correctness).
Disabled by default until we have inlined function
bodies and confirmation of no regression and equality
of binaries.
For #6110 .
For #1909 .
This change depends on:
https://go-review.googlesource.com/16220
https://go-review.googlesource.com/16222
(already submitted) for all.bash to work.
Some initial export data sizes for std lib packages. This data
is without exported functions with inlineable function bodies.
