Somewhat notably, this means long if statement chains are now parsed
recursively, rather than iteratively. This shouldn't be a concern
though, as several other functions (e.g., gen, typecheck, walk)
already use recursion to process the parsed if statement Node trees.

Merge push_parser and pop_parser into a single parse_import function
and inline unimportfile. Shake out function boundaries a little bit so
that the symmetry is readily visible.
Move the import_package call into parse_import (and inline
import_there into import_package). This means importfile no longer
needs to provide fake import data to be needlessly lexed/parsed every
time it's called.
Also, instead of indicating import success/failure by whether the next
token is "package", import_spec can just check whether importpkg is
non-nil.
Tangentially, this somehow alters the diagnostics produced for
test/fixedbugs/issue11610.go. However, the new diagnostics are more
consistent with those produced when the empty import statement is
absent, which seems more desirable than maintaining the previous
errors.

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.

Previously, the builtin runtime export data was reparsed before every
Go source file, and the unsafe export data was reparsed for every
import of package unsafe. Now, we parse both of them just once ahead
of time.
This does mean package unsafe's export data will be loaded even when
compiling packages that don't import it, but it's tiny anyway.

The go/build parser accepts "//+build", with no spaces.
Make the cmd/dist bootstrap parser do the same.
While in theory we should always use the space form,
I copied some code that did not into the standard tree,
and I was very confused that 'go test' had had no problem
but then make.bash died.
(As a reminder, cmd/dist does not use go/build because
cmd/dist must build against earlier versions of Go.)

Changes largely in preparation for eventually switching the builtin
export data to use the new binary format.
Replace fancy incremental line-by-line scanning with simply reading
the entire object file into memory, finding the export data section,
and processing it that way.
Just use "package runtime" and "package unsafe" in the builtin Go
source files so we don't need to rewrite references to "PACKAGE".
Stop looking for init_PACKAGE_function; it doesn't exist anyway.
Compile package runtime with -u so that its export data marks it as a
"safe" package.
Eliminate requirement to pass "runtime" and "unsafe" as command-line
arguments so that just "go run mkbuiltin.go" works.
Only rewrite builtin.go when successful.
