Alan Donovan b56ef30191 tools: updates for minimum Go version 1.6
Details:
- remove go1.5 "default version" labels on most files
- 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.

Alan Donovan 542ffc7e75 tools: switch to standard go/types at tip
A few files have been forked and tagged "go1.5,!go1.6" to work around
minor API changes between the two types packages:
- constant.Value.String() in oracle/describe.go and its tests;
- 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).

Alan Donovan 2477c0d578 x/tools/...: fork and tag !1.5 all files that use go/types et al
This change will ensure that the tree continues to work with go1.4.1.

All files continue to depend on golang.org/x/tools/go/types, but in a
follow-up change, I will switch the primary files to depend on the
standard go/types package.  Another (smaller) set of files will be
forked and tagged, this time !1.6, due to API differences between the
two packages.

All tests pass using 1.4.1, 1.5, and ~1.6 (tip).

Alan Donovan 868c429971 go/ssa/interp: fix bug causing subelements of aggregates to change address.
Since all SSA values are immutable, no value copying is required for
any operations except those that load from or store to a variable;
those operations must do an aggregate copy, i.e., descend into struct
and array elements.  All other calls to copyVal have been removed;
they were pieces of duct tape, as I had long suspected.

The descent must be based on the static type information, not the
"shape" of the dynamic value, since two reflect.Value structs may have
different internal shapes.  We clobber the true definition of
reflect.Value's underlying type, replacing it with struct{interface{},
interface{}}, which is close enough to make the load/store functions
work.

+ Test

Alan Donovan 744d7e68b1 go.tools/go/ssa: use bytes.Buffer instead of io.Writer.
This is (a) more efficient and (b) avoids the need for
constant error handling, since buffer writes can't fail.

Also:
- added WriteFunction and WritePackage functions,
  similar to types.WriteFoo.
- *Function and *Package now implement io.WriterTo.
