0d9474206f exp/types/staging: more flexible API, cleanups
- Changed Check signature to take function parameters for
  more flexibility: Now a client can interrupt type checking
  early (via panic in one the upcalls) once the desired
  type information or number of errors is reached. Default
  use is still simple.

- Cleaned up main typechecking loops. Now does not neglect
  _ declarations anymore.

- Various other cleanups.

328f0e7f2e exp/types/staging: test drivers
This code has been reviewed before. The most significant
change is to check_test which now can handle more than
one error at the same error position (due to spurious
errors - should not happen in praxis once error handling
has been fine-tuned). This change makes check_test easier
to use during development.

51e8fe5b1b cmd/gc: don't dereference a nil Type pointer in widstruct
The nil dereference in the next few lines doesn't seem
to cause a segmentation fault on Unix, but does seem
to halt the Go compiler.

The following is a test case:

>>>
package main

func mine(int b) int {
        return b + 2
}

func main() {
        mine()

        c = mine()
}
<<<

Without this change only the following is caught:

typecheck.go:3: undefined: b
typecheck.go:4: undefined: b

with it, we catch all the errors:

typecheck.go:3: undefined: b
typecheck.go:4: undefined: b
typecheck.go:10: undefined: c
typecheck.go:10: cannot assign to c .

0b9fe6d24e image/jpeg: move the level-shift and clip out of the idct function,
to be consistent with the fdct function, and to ease any future
idct rewrites in assembly.

The BenchmarkIDCT delta is obviously just an accounting change and not
a real saving, but it does give an indication of what proportion of
time was spent in the actual IDCT and what proportion was in shift and
clip. The idct time taken is now comparable to fdct.

The BenchmarkFDCT delta is an estimate of benchmark noise.

f2444f0bc1 image/jpeg: clean up BenchmarkDecode and BenchmarkEncode to not
refer to opacity. Those references were copy/pasted from the
image/png encoding benchmarks, which cares whether or not the
source image is opaque, but the JPEG encoder does not care.

12e343f372 image/jpeg: add DCT tests, do a small optimization (common sub-expression
elimination) in idct.go.

benchmark                   old ns/op    new ns/op    delta

BenchmarkDecodeRGBOpaque      2948607      2941051   -0.26%

The "type block" declaration moved so that idct.go is compilable
as a stand-alone file: "go tool 6g -S idct.go" works.
