Now that we've removed the necessity for subscripts in importers, we can
effectively eliminate them from the the type parameter API by removing
them from the type string.

When running benchmarks with high -count and no tests (either at all or
filtered with -run), the time for runTests to check for tests -count
times can add a significant delay to starting benchmarks.
To avoid this delay, make runTests bail out on the second iteration if
the first found no tests to run. We expect the same tests to run every
time, so there is no reason to duplicate work.
One caveat: the testing docs do not explicitly require the same subtests
to be run on every call, so this could break tests that depend on
multiple runs to actually run all tests. I consider such tests invalid,
but some may exist.

This introduces a number of new classifications which will make it
easier to generate functions to assemble the new instructions of
ISA 3.1, and potentially earlier versions.
No code generation changes should occur as a result of these. These
allow finer control over how an opcode is matched to an optab entry.
Literal values are now classified based on the smallest number of bits
needed to encode, and matching rules will accept a literal if it
can be zero/sign extended to fit a larger literal class.
Likewise, support classifying even register numbers for GPR, VSX, and
FPR instructions. Some instructions require and even/odd register pair,
and these are usually represented by specifying the even register, and
similarly encoded.
Likewise, add a unit test for the argument classifier function (aclass).
This caught an off-by-one bug in aclass which is also fixed.

In CL 327872, there's a fix for crawling of embeddable types directly
reached by the user, so all of its methods need to be re-exported. But
we missed the cased when an un-exported type may be reachable by
embedding in exported type. Example:
type t struct {}
func (t) M() {}
func F() interface{} { return struct{ t }{} }
We generate the wrapper for "struct{ t }".M, and when inlining call to
"struct{ t }".M makes "t.M" reachable.
It works well, and only be revealed in CL 327871, when we changed
methodWrapper to always call inline.InlineCalls, thus causes the crash
in #49016, which involve dot type in inlined function.
