After go1.10, compiler/linker option flags apply only to the packages
listed directly on the command line unless the matching pattern is
specified. For debugging, we want to apply the flags to all packages.

GOMIPS is a GOARCH=mips{,le} specific option, for a choice between
hard-float and soft-float. Valid values are 'hardfloat' (default) and
'softfloat'. It is passed to the assembler as
'GOMIPS_{hardfloat,softfloat}'.
Note: GOMIPS will later also be used for a choice of MIPS instruction
set (mips32/mips32r2).

If people are interested in contributing to Go, but not sure what
change they'd like to make just yet, we can point them to the scratch
repo, so they can go through the process of submitting and merging
something now, and make more useful contributions later.
My evidence that sending people to the scratch repo would encourage
future contributions is that a number of people who went through the
workshop at Gophercon have continued to send CL's after submitting to
the scratch repo, even though I doubt they planned to before going
through the workshop.

A method expression is of the form T.m where T is a type and m
is a method of that type. The spec restricted T essentially to
a type name. Both cmd/compile and go/types accepted any type
syntactically, and a method expression was really just a form
of a selector expression x.f where x denotes a type.
This CL removes the spec syntax restriction from MethodExpr
to match the actual implementation. It also moves MethodExpr
from Operand to PrimaryExpr, because that's what it is.
It still keeps the separate notion of MethodExpr even though
it looks just like a selector expresion, since a MethodExpr
must start with a type rather than a value, and the spec's
syntax expresses this bit of semantics via distinct productions
(e.g., conversions look like calls but also must start with
a type).
Fixes#9060.

https://golang.org/cl/71750 specifies iota values as indices,
thus making them independent from nested constant declarations.
This CL removes some of the comments in the examples that were
still referring to the old notion of iotas being incremented
and reset.
As an aside, please note that the spec still permits the use
of iota in a nested function (like before). Specifically, the
following cases are permitted by the spec (as before):
1) const _ = len([iota]int{})
2) const _ = unsafe.Sizeof(func(){ _ = iota })
For #15550.

Issue #15550 is clearly an esoteric case but the spec was silent
about it and we had diverging implementations. By making `iota`
and index that is relative to the respective constant declaration,
nested const declarations won't affect outer values of `iota`.
cmd/compile and go/types already follow this semantics.
Fixes#15550.
