The compiler chooses the literal value export format by type
not by constant.Kind. That is, a floating-point constant is
always exported as a (big) float value, not a (big) rational
value, even though the internal representation may be that
of a rational number. (This is a possibility now that the
compiler also uses the go/constant package.)
Naturally, during import, a floating-point value is read as
a float and represented as a (big) float in go/constant.
The types2 importer (based on the go/types importer) read
the floating-point number elements (mantissa, exponent) but
then constructed the float go/constant value through a series
of elementary operations, typically leading to a rational,
but sometimes even an integer number (e.g. for math.MaxFloat64).
There is no problem with that (the value is the same) but if
we want to impose bitsize limits on overlarge integer values
we quickly run into trouble with large floats represented as
integers.
This change matches the code importing float literals with
the code used by the compiler.
Note: At some point we may want to relax the import/export code
for constant values and export them by representation rather than
by type. As is, we lose accuracy since all floating-point point
values, even the ones internally represented as rational numbers
end up being exported as floating-point numbers.

In the linker's deadcode pass we decode type symbols for
interface satisfaction analysis. When linking against Go shared
libraries, the type symbol may come from a shared library, so it
doesn't have data in the current module being linked, so we cannot
decode it. We already have code to skip DYNIMPORT symbols. However,
this doesn't actually work, because at that point the type symbols'
names haven't been mangled, whereas they may be mangled in the
shared library. So the symbol definition (in shared library) and
reference (in current module) haven't been connected.
Skip decoding type symbols of type Sxxx (along with DYNIMPORT)
when linkShared.
Note: we cannot skip all type symbols, as we still need to mark
unexported methods defined in the current module.

We add entries to the defer list at panic/goexit time on-the-fly for
frames with open-coded defers. We do this so that we can correctly
process open-coded defers and non-open-coded defers in the correct order
during panics/goexits. But we need to remove entries for open-coded
defers from the defer list when there is a recover, since those entries
may never get removed otherwise and will get stale, since their
corresponding defers may now be processed normally (inline).
This bug here is that we were only removing higher-up stale entries
during a recover if all defers in the current frame were done. But we
could have more defers in the current frame (as the new test case
shows). In this case, we need to leave the current defer entry around
for use by deferreturn, but still remove any stale entries further along
the chain.
For bug 43921, simple change that we should abort the removal loop for
any defer entry that is started (i.e. in process by a still
not-recovered outer panic), even if it is not an open-coded defer.
This change does not fix bug 43920, which looks to be a more complex fix.

The recent refactoring of SelectorExpr code to helpers broke the
handling of MethodExprs when there is an embedded field involved (e.g.
test/method7.go, line 48). If there is an embedded field involved, the
node op seen in DotMethod() is an ODOT rather than an OTYPE. Also, the
receiver type of the result should be the original type, but the new
code was using the last type after following the embedding path.

go/constant represents a Float constant either as a rational number
(if numerator and denominator are small enough), or, as a "catch-all",
as a arbitrary-precision floating-point number.
This CL cleans up some of these transitions by factoring out more
of the decision logic and documents the rationale between the state
transitions better.
This CL also simplifies some unrelated code that was overly complex.
