Running the interpreter on (most of) the tests package in
"encoding" unearthed a couple of ssa.builder bugs, already
fixed. This CL contains the interpreter fixes that were
required. (The "encoding" tests aren't added to the suite
since they're slow.)
Added intrinsics for:
math.Exp
math.Min
hash/crc32.haveSSE42
(reflect.Type).Field
(reflect.Type).NumField
(reflect.Type).NumMethod
reflect.New
(reflect.Value).NumMethod
syscall.RawSyscall (returns ENOSYS)
reflect.Set (a no-op)
Treat unsafe.Pointer -> *T conversions by returning new(T).
This is incorrect but at least preserves type-safety,
which is sufficient for these tests.
hashmap: treat nil *hashmap as an empty map.

stdlib_test runs the builder (in sanity-checking mode) over
the Go standard library. It also prints some stats about
the time and memory usage.
Also:
- importer.LoadPackage too (not just doImport) must consult
the cache to avoid creating duplicate Package instances for
the same import path when called serially from a test.
- importer: skip empty directories without an error.
- importer: print all errors, not just the first.
- visit.go: added AllFunctions utility for enumerating all
Functions in a Program.
- ssa.MethodSet is not safe to expose from the package since
it must be accessed under an (inaccessible) lock. (!!!)
This CL makes it unexported and restricts its use to the
single function Program.LookupMethod().
- Program.MethodSet() has gone.
Clients should instead iterate over the types.MethodSet
and call LookupMethod.
- Package.DumpTo(): improved efficiency of methodset printing
(by not creating wrappers) and accuracy (by showing * on
receiver type only when necessary).
- Program.CreatePackage: documented precondition and added
assertion.

- implemented objset for tracking duplicates of fields and methods
which permitted a simpler and faster scope implementation in turn
- related cleanups and internal renames
- fixed a couple of identifier reporting bugs
Speed of type-checking itself increased by almost 10%
(from ~71Kloc/s to ~78Kloc/s on one machine, measured
via go test -run=Self).

We use the new field to determine whether or not a function is
synthetic, not Pos() == 0, so synthetic functions can have
positions too.

- First step towards unified use of scopes. Will enable
further simplifications.
- Removed various ForEach iterators in favor of the existing
accessor methods, for a thinner API.
- Renamed outer/Outer to parent/Parent for scopes.
- Removed check.lookup in favor of Scope.LookupParent.

Implement Pos() method for
Values: Parameter, Capture, Phi. (Not Literal, Builtin.)
Instructions: UnOp, BinOp, Store.
'address' (an lvalue) now needs position of '*' in "*addr".
Also:
- Un-export fields Pos_ Type_ Name_ Block_ from various values/instructions.
Define NewFunction() as a temporary measure.
Will try to eliminate calls from clients...
- Remove Implements{Value,Member,Interface} marker methods.
I've decided I don't like them.
- Func.addParamObj helper.
- Various comment fixes.

They will be deleted from their current homes once this has landed.
Changes made to import paths to make the code compile, and to find
errchk in the right place in cmd/vet's Makefile.
TODO in a later CL: tidy up vet.
