This is a port of CL 289049 to go/types. In that CL, tests were written
using the ability of tests/run.go to generate test packages dynamically.
For this CL, similar functionality is added to the go/types errmap
tests: tests are refactored to decouple the loading of source code from
the filesystem, so that tests for long constants may be generated
dynamically rather than checked-in as a large testdata file.

Rejecting backslash introduces problems with presenting
underlying OS file systems that contain names with backslash.
Rejecting backslash also does not Windows-proof the syntax,
because colon can also be a path separator. And we are not
going to reject colon from all names. So don't reject backslash
either.
There is a similar problem on Windows with names containing
slashes, but those are more difficult (though not impossible)
to create.
Also document and enforce that paths must be UTF-8.

For functions that call reflect.Type.Method (or MethodByName), we
mark it as REFLECTMETHOD, which tells the linker that methods
can be retrieved via reflection and the linker keeps all exported
methods live. Currently, this marking expects exactly the
interface call reflect.Type.Method (or MethodByName). But now the
compiler can devirtualize that call to a concrete call
reflect.(*rtype).Method (or MethodByName), which is not handled
and causing the linker to discard methods too aggressively.
Handle the latter in this CL.

0-padding, and paddings of other sorts weren't handled and we assumed
that only non-padded decimal lengths would be passed in.
Added test cases to ensure that the parsing still proceeds as expected.
The prior crashing repro:
0000000000000000000000000000000030 mtime=1432668921.098285006\n30 ctime=2147483649.15163319
exposed the fallacy in the code, that assumed that the length would ALWAYS be a
non-padded decimal length string.
This bug has existed since Go1.1 as per CL 6700047.
Thanks to Josh Bleecher Snyder for fuzzing this package, and thanks to Tom
Thorogood for advocacy, raising parity with GNU Tar, but for providing more test cases.

- move the check for main function signature to resolver.go, to be
consistent with init. Also, update uses of _InvalidInitSig to
_InvalidInitDecl, consistent with what we decided for dev.regabi.
- Update some tests in api_test.go which newly fail after CL 289715
(fixing reporting of untyped nil) In all cases but one, these updates
were consistent with types2. However, in one case types2 seems to be
able to resolve more type information than go/types for a broken
package. I left a TODO to investigate this further.

This is a port of CL 284052 to go/types. The port is not entirely
faithful, as untyped conversion has been refactored in go/types.
Additionally, a comment was added to reference issue #13061 in the
implicitType method.
For #13061

Disabled test/typeparam/fact.go for now as there's an issue
with stenciling.

- Handle generic function calling itself or another generic function in
stenciling. This is easy - after it is created, just scan an
instantiated generic function for function instantiations (that may
needed to be stenciled), just like non-generic functions. The types
in the function instantiation will already have been set by the
stenciling.
- Handle OTYPE nodes in subster.node() (allows for generic type
conversions).
- Eliminated some duplicated work in subster.typ().
- Added new test case fact.go that tests a generic function calling
itself, and simple generic type conversions.
- Cause an error if a generic function is to be exported (which we
don't handle yet).
- Fixed some suggested changes in the add.go test case that I missed in
the last review.

Now that we have a g register, just use it.
Note: functions that can be called from ABI0 context (e.g.
morestack) is unchanged. Functions that switch g is also
unchanged, because we need to set the new g in both the register
and TLS.
