cmd/compile: match Go 1.17 compiler error messages more closely
When being used by the compiler, fix up types2 error messages to be more
like Go 1.17 compiler errors. In particular:
- add information about which method is missing when a type is not
assignable/convertible/etc. to an interface.
- add information about any existing method which has the same name,
but wrong type.
- add extra hint in the case that the source or destination type is a
pointer to an interface, rather than an interface.
- add extra hint "need type assertion" in the case that the source is
an interface that is implemented by the destination.
- the following change in the CL stack also adds information about any
existing method with a different name that only differs in case.
Include much of the new logic in a new common function
(*Checker).missingMethodReason().
types2 still adds a little more information in some cases then the Go
1.17 compiler. For example, it typically says "(value of type T)",
rather than "(type T)", where "value" could also be "constant",
"variable", etc.
I kept the types2 error messages almost all the same when types2 is not
used by the compiler. The only change (to reduce amount of compatibility
code) was to change "M method" phrasing in one case to "method M"
phrasing in one error message (which is the phrasing it uses in all
other cases). That is the reason that there are a few small changes in
types2/testdata/check/*.src.
Added new test test/fixedbugs/issue48471.go to test that the added
information is appearing correctly.
Also adjusted the pattern matching in a bunch of other
test/fixedbugs/*.go, now that types2 is producing error messages closer
to Go 1.17. Was able to remove a couple test files from the types2
exception list in run.go.
Updated #48471

cmd/compile: rewrite f(g()) for multi-value g() during typecheck
This is a re-attempt at CL 153841, which caused two regressions: 1. crypto/ecdsa failed to build with -gcflags=-l=4. This was because when "t1, t2, ... := g(); f(t1, t2, ...)" was exported, we were losing the first assignment from the call's Ninit field. 2. net/http/pprof failed to run with -gcflags=-N. This is due to a conflict with CL 159717: as of that CL, package-scope initialization statements are executed within the "init.ializer" function, rather than the "init" function, and the generated temp variables need to be moved accordingly too. [Rest of description is as before.] This CL moves order.go's copyRet logic for rewriting f(g()) into t1, t2, ... := g(); f(t1, t2, ...) earlier into typecheck. This allows the rest of the compiler to stop worrying about multi-value functions appearing outside of OAS2FUNC nodes. This changes compiler behavior in a few observable ways: 1. Typechecking error messages for builtin functions now use general case error messages rather than unnecessarily differing ones. 2. Because f(g()) is rewritten before inlining, saved inline bodies now see the rewritten form too. This could be addressed, but doesn't seem worthwhile. 3. Most notably, this simplifies escape analysis and fixes a memory corruption issue in esc.go. See #29197 for details. Fixes #15992. Fixes #29197.

cmd/internal/gc: detect bad append(f()) during type check
Today's earlier fix can stay, but it's a band-aid over the real problem, which is that bad code was slipping through the type checker into the back end (and luckily causing a type error there). I discovered this because my new append does not use the same temporaries and failed the test as written. Fixes #9521.
