No longer assume that e_lfanew (in the IMAGE_DOS_HEADER strcuture) is always one byte. It is now regarded as a 4 byte uint32.
Fixes#4177.

- 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.

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.

2. add support for R_ARM_PC24 and R_ARM_JUMP24
3. refactor, remove D_PLT32 in favor of D_CALL

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 .

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.
