Select and switch statements only ever contain case statements, so
change their Cases fields from Nodes to []*CaseStmt. This allows
removing a bunch of type assertions throughout the compiler.
CaseStmt should be renamed to CaseClause, and SelectStmt should
probably have its own CommClause type instead (like in go/ast and
cmd/compile/internal/syntax), but this is a good start.

ODOTMETH is unique among SelectorExpr expressions, in that Sel gets
mangled so that it no longer has the original identifier that was
selected (e.g., just "Foo"), but instead the qualified symbol name for
the selected method (e.g., "pkg.Type.Foo"). This is rarely useful, and
instead results in a lot of compiler code needing to worry about
undoing this change.
This CL changes ODOTMETH to leave the original symbol in place. The
handful of code locations where the mangled symbol name is actually
wanted are updated to use ir.MethodExprName(n).Sym() or (equivalently)
ir.MethodExprName(n).Func.Sym() instead.
Historically, the compiler backend has mistakenly used types.Syms
where it should have used ir.Name/ir.Funcs. And this change in
particular may risk breaking something, as the SelectorExpr.Sel will
no longer point at a symbol that uniquely identifies the called
method. However, I expect CL 280294 (desugar OCALLMETH into OCALLFUNC)
to have substantially reduced this risk, as ODOTMETH expressions are
now replaced entirely earlier in the compiler.

This CL cleans up a few minor points in walkExpr:
1. We don't actually care about computing the type-size of all
expressions that are walked. We care about computing the type-size of
all expressions that are *returned* by walk, as these are the
expressions that will actually be seen by the back end.
2. There's no need to call typecheck.EvalConst anymore. EvalConst used
to be responsible for doing additional constant folding during walk;
but for a while a now, it has done only as much constant folding as is
required during type checking (because doing further constant folding
led to too many issues with Go spec compliance). Instead, more
aggressive constant folding is handled entirely by SSA.
3. The code for detecting string constants and generating their
symbols can be simplified somewhat.

with no X expression), and leaves a lot of duplicate work for the rest

Within the compiler, we represent the type of methods as a special
"method" type, where the receiver parameter type is kept separate from
the other parameters. This is convenient for operations like testing
whether a type implements an interface, where we want to ignore the
receiver type.
These method types don't properly exist within the Go language though:
there are only "function" types. E.g., method expressions (expressions
of the form Type.Method) are simply functions with the receiver
parameter prepended to the regular parameter list.
However, the compiler backend is currently a little sloppy in its
handling of these types, which results in temporary variables being
declared as having "method" type, which then end up in DWARF
data. This is probably harmless in practice, but it's still wrong.
The proper solution is to fix the backend code so that we use correct
types everywhere, and the next CL does exactly this. But as it fixes
the DWARF output, so it fails toolstash -cmp. So this prelim CL
bandages over the issue in a way that generates the same output as
that proper fix.

The assignment type-checking code previously bounced around a lot
between the LHS and RHS sides of the assignment. But there's actually
a very simple, consistent pattern to how to type check assignments:
1. Check the RHS expression.
2. If the LHS expression is an identifier that was declared in this
statement and it doesn't have an explicit type, give it the RHS
expression's default type.
3. Check the LHS expression.
4. Try assigning the RHS expression to the LHS expression, adding
implicit conversions as needed.
This CL implements this algorithm, and refactors tcAssign and
tcAssignList to use a common implementation. It also fixes the error
messages to consistently say just "1 variable" or "1 value", rather
than occasionally "1 variables" or "1 values".

Today, timeHistogram, when copied, has the wrong set of counts for the
bucket that should represent (-inf, 0), when in fact it contains [0, 1).
In essence, the buckets are all shifted over by one from where they're
supposed to be.
But this also means that the existence of the overflow bucket is wrong:
the top bucket is supposed to extend to infinity, and what we're really
missing is an underflow bucket to represent the range (-inf, 0).
We could just always zero this bucket and continue ignoring negative
durations, but that likely isn't prudent.
timeHistogram is intended to be used with differences in nanotime, but
depending on how a platform is implemented (or due to a bug in that
platform) it's possible to get a negative duration without having done
anything wrong. We should just be resilient to that and be able to
detect it.
So this change removes the overflow bucket and replaces it with an
underflow bucket, and timeHistogram no longer panics when faced with a
negative duration.
