The previous "dead φ" check was simple and naive but left cycles of
dead φ-nodes. This confused some downstream static analysis tools.
This change makes the φ-nodes liveness check transitive.

Also, number phi nodes so they're not all called t0 during debugging.
Reduces memory consumption by 1%.

- 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

The export data formats (text and binary) emitted by gc in Go 1.7 did
not record the package that "owns" each blank field, even though blank
is an unexported identifier. Before, gcimporter would assume the
package of the export data file owns blank fields within it, even
blank fields reexported from another package. As a result, identical
types would become nonidentical during reexporting.
For bug compatibility with gc, gcimporter now treats blank fields as
if they all belong to the same dummy package, avoiding spurious "can't
assign A to B" errors in tools based on go/types.

...to match the new interface between "go test" and the standard testing
package.
Rather than generate SSA code directly, which was tricky and fragile, we
now generate source just as "go test" does, type-check it, and build an
SSA package from it. crawshaw suggested I do this in the very first
version of testmain.go, but at the time I believed it to be infeasible.
The testMainStartBodyHook mechanism has gone away; installations that
needed it can now achieve the same results more easily by overriding the
templates.
Tested with Go 1.6, 1.7 and 1.8.

Allow extra arguments to be passed to the specified gccgo compiler
when it is called in GccgoInstallation.InitFromDriver. This allows
the call to gccgo to be adjusted depending on the build environment.
For example, some build environments require the
'no-canonical-prefixes' option to prevent gccgo from resolving
symlinks when generating relative prefixes.
