- remove go1.6 labels on a few files
- go/loader: use conf.Cwd not "." in a couple places; update faulty
test expectations. (Not sure why this wasn't caught sooner.)
- go/ssa/interp: add 'mono' result to time.now intrinsic
- go/gcimporter15/bimport.go: make consistent with the version in gc
- go/ssa/interp: update test error message
- go/ssa: update a comment
The go/gcimporter15/bexport.go logic is stale and needs to be brought
up to date. Needs a separate CL since it's tricky.
Tested on go1.6, go1.7, go1.8.

This reduces the amount of manual steps that need to be taken
when using gorename.
All occurrences of the old identifier are updated in the doc.
The update is done using a regex to ensure that we replace

Because go/types is slightly more strict than gc about certain "soft"
errors (ones that aren't necessary to interpret a Go program), gorename
rejects programs that compile under gc. This change relaxes gorename's
error checks so that they are weaker than gc's.
This is a workaround for issue golang/go#14596 in gorename,
whose underlying problem is issue golang/go#8560 in gc.

I felt the burn of my laptop on my legs, spinning away while processing
goimports, and felt that it was time to make goimports great again.
Over the past few years goimports fell into a slow state of disrepair
with too many feature additions and no attention to the performance
death by a thousand cuts. This was particularly terrible on OS X with
its lackluster filesystem buffering.
This CL makes goimports stronger, together with various optimizations
and more visibility into what goimports is doing.
* adds more internal documentation
* avoids scanning $GOPATH for answers when running goimports on a file
under $GOROOT (for Go core hackers)
* don't read all $GOROOT & $GOPATH directories' Go code looking for
their package names until much later. Require the package name of
missing imports to be present in the last two directory path
components. Then only try importing them in order from best to
worst (shortest to longest, as before), so we can stop early.
* when adding imports, add names to imports when the imported package name
doesn't match the baes of its import path. For example:
import foo "example.net/foo/v1"
* don't read all *.go files in a package directory once the first file
in a directory has revealed itself to be a package we're not looking
for. For example, if we're looking for the right "client" for "client.Foo",
we used to consider a directory "bar/client" as a candidate and read
all 50 of its *.go files instead of stopping after its first *.go
file had a "package main" line.
* add some fast paths to remove allocations
* add some fast paths to remove disk I/O when looking up the base
package name of a standard library import (of existing imports in a
file, which are very common)
* adds a special case for import "C", to avoid some disk I/O.
* add a -verbose flag to goimports for debugging
On my Mac laptop with a huge $GOPATH, with a test file like:
package foo
import (
"fmt"
"net/http"
)
/*
*/
import "C"
var _ = cloudbilling.New
var _ = http.NewRequest
var _ = client.New
... this took like 10 seconds before, and now 1.3 seconds. (Still
slow; disk-based caching can come later)

- constant.ToInt must now be called before constant.Int64Val.
- types.Config{Importer: importer.Default()} in a number of places
- go/types/typeutil/import_test.go uses lowercase names to avoid 'import "C"'.
Files in go/types/typesutil, missing from my previous CL, have been
tagged !go1.5; these files will be deleted in February.
All affected packages were tested using 1.4.1, 1.5, and ~1.6 (tip).

Use an concurrency-limiting semaphore to reduce I/O parallelism in Import.
Also, start the producer in a new goroutine so that it runs in parallel
with the consumer. Paradoxically, this reduces the peak number of
goroutines.
Also, in buildutil.ForEachPackage, make the concurrency limiting
semaphore global, since I/O parallelism is a process-wide resource.

The optional Qualifier function determines what prefix to attach to
package-level names, enabling clients to qualify packages in different
ways, for example, using only the package name instead of its complete
path, or using the locally appropriate name for package given a set of
(possibly renaming) imports.
Prior to this change, clients wanting this behavior had to copy
hundreds of lines of complex printing logic.
Fun fact: (*types.Package).Path and (*types.Package).Name are valid
Qualifier functions.
We provide the RelativeTo helper function to create Qualifiers so that
the old behavior remains a one-liner.
