The minimum bootstrap version for Go ≥ 1.20 is Go 1.17. That version
supports the new style //go:build lines. Thus the old style //+build
lines can be dropped in this part of the tree as well. Leave the
//+build lines in cmd/dist which will ensure the minimum Go version
during bootstrap.
As suggested by Cherry during review of CL 430496

CL 413374 added syscall.Mmap on solaris. Use it in cmd/compile and
cmd/link if the bootstrap toolchain is Go ≥ 1.20.

After we deprecated reflect.{SliceHeader, StringHeader}, it is recommended
to use unsafe.{Slice, String} to replace its work. However, the compiler
and linker cannot be migrated for the time being.
As a temporary strategy, using the "internal/unsafeheader" package like
other code is the most suitable choice at present.

Go 1.17 will be used instead of Go 1.4 as minimum required version for
bootstrap, so runtime.KeepAlive introduced in Go 1.7 can be used in
cmd/compile.

This CL restructures the gcimports importer to mmap the export data
into memory as a string, and then pass that same string to both the
typecheck and types2 importers.
This is primarily motivated by preparation for unified IR; but it
should also improve performance (fewer string copies) and reduces
divergance between the two importers.
Passes toolstash -cmp.
