cmd/compile: rewrite code to omit many nodeSeq calls
...
This CL was automatically generated using a special-purpose AST
rewriting tool, followed by manual editing to put some comments back in
the right places and fix some bad line breaks.
The result is not perfect but it's a big step toward getting back to
sanity, and because it was automatically generated there is a decent
chance that it is correct.
Passes toolstash -cmp.
Update #14473 .

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

all: single space after period.
...
The tree's pretty inconsistent about single space vs double space
after a period in documentation. Make it consistently a single space,
per earlier decisions. This means contributors won't be confused by
misleading precedence.
This CL doesn't use go/doc to parse. It only addresses // comments.
It was generated with:
$ perl -i -npe 's,^(\s*// .+[a-z]\.) +([A-Z]),$1 $2,' $(git grep -l -E '^\s*//(.+\.) +([A-Z])')
$ go test go/doc -update

Type Op is enfored now.
Type EType will need further CLs.
Added TODOs where Node.EType is used as a union type.
The TODOs have the format `TODO(marvin): Fix Node.EType union type.`.
Furthermore:
-The flag of Econv function in fmt.go is removed, since unused.
-Some cleaning along the way, e.g. declare vars first when getting initialized.
Passes go build -toolexec 'toolstash -cmp' -a std.

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.
