Alan Donovan d3f2df4854 go.tools/go/ssa/interp: some fixes to tests
- Break out parts of coverage.go into more specific files.
- Re-enable test of nil interface-to-interface conversion.
- Update initorder test to reflect spec ambiguity and gc vs go/types variance.
- Re-enable test dependent on now-fixed bug 8189 ("value,ok" yields an untyped bool)

Alan Donovan b2ea2e8560 go.tools/go/ssa: permit "for range x"
+ test

Also: don't generate init() functions for packages loaded from export data.

Alan Donovan 6db8a00c75 go.tools/go/ssa: write zero value when storing a composite literal in-place if necessary
Previously, statements such as:

type T struct { a, b int }
[...]
x = T{}
x = T{b: 1}

would only affect the aggregate members mentioned in the composite
literal and leave the other members unchanged. This change causes us
to write a zero value to the target in cases where the target is not
already known to hold a zero value and the number of initializers in
the composite literal differs from the number of elements in its type.

Author: Peter Collingbourne.  (hg clpatch got confused)

Alan Donovan de23e2b0c2 go/ssa: make Builtin capable of representing non-spec-defined intrinsics.
Also, define ssa:wrapnilchk intrinsic to check and gracefully
fail when a T method is dynamically invoked via a nil *T receiver.
+ Test.

A follow-up CL will add another intrinsic, ssa:memclr.

+ minor cleanups.

Robert Griesemer 0fa48054ca go.tools/go/types: comma-ok expressions return bool rather than untyped bool
Per the current spec.

Fixes golang/go#8188.

Robert Griesemer 3827909f21 go.tools/go/types: compute correct initialization order
- Replaced check.initDependencies with check.initOrder;
  this is the only semantic change, it affects only the
  value of Info.InitOrder.
- Added additional init order test cases and adjusted
  existing tests.
- Moved orderedSetObjects from resolver.go to ordering.go.

Fixes golang/go#7964.

Alan Donovan 7d1d69032b go.tools/go/ssa: don't attempt fusion on single-pred blocks with φ-nodes
During block optimization, degenerate conditional logic such
as "false && x" may result in single-predecessor blocks
containing φ-nodes.  (Ideally such φ-nodes would be replaced
by their sole operand, but that requires Referrers information
which isn't computed until later.)  It is obviously not safe
to fuse such blocks, so now we don't.

Fixes golang/go#7840
