Alan Donovan ced954c167 go.tools/go/types: split Info.Objects map into Defs and Uses.
An identifier X in anonymous struct field struct{X} is both a
definition of a field (*Var) and reference to a type
(*TypeName).  Now that we have split the map, we can capture
both of these aspects.

Interestingly, every client but one was going to extra effort
to iterate over just the uses or just the defs; this
simplifies them.

Also, fix two bug related to tagless switches:
- An entry was being recorded in the Object map for a piece of
  synthetic syntax.
- The "true" identifier was being looked up in the current scope,
  which allowed perverse users to locally redefine it.  Now
  we use the bool (not untyped boolean) constant true, per the
  consequent clarification of the spec (issue 7404).

+ tests.

Fixes golang/go#7276

Alan Donovan ed45af74ff go.tools/go/loader: add AllowTypeErrors flag.
If this flag is set, (*Config).Load will not return an
error even if some packages had type errors.  Each individual
PackageInfo can be queried for its error state, now exposed as
TypeError.

In addition, each PackageInfo exposes whether it is
"transitively error-free".  ssa.Create skips packages without
this flag since it is required for SSA construction.

+ Test.

Alan Donovan 08fadac071 go.tools/go/loader: simplify command-line syntax.
Previously, each word could be a package import path or a
comma-separated list of *.go file names.  Now, if the
first word ends with ".go", all words are assumed to be
Go source files.  This makes it impossible to specify
two ad-hoc packages from source files, but no-one needs that.

FromArgs also takes a boolean indicating whether tests
are wanted or not.

Also: ssadump: add -test flag to set that boolean.
For the oracle it's always true.

Alan Donovan 64ec206bfd go.tools/go/types: combine Info.{Types,Values} maps.
This results in significant improvement to type-checking time:
it reduces by 4% the entire running time of ssa/stdlib_test
(GOMAXPROCS=8, n=7).

Alan Donovan 0dcaae1610 go.tools/go/loader: permit Create* methods to specify the ad-hoc package's path
CL 49530047 made the (over-)simplifying assumption that the
Path of an ad-hoc (Created) package should default to its
Name, i.e. package declaration.

With this change, the Name is still always computed from the
package declaration (by go/types) but the Path may be
specified by the loader.Config.  If "", the value of the Name
is used, which is not globally unique.

Alan Donovan 3fc0fc1310 go.tools: rename packages.
Was:		Now:
ssa		go/ssa
importer	go/loader
pointer		go/pointer

Next CL: call -> go/callgraph (requires more care)
