Couple of changes to the linker's dwarf test, including:

 - add some code to the DWARF tests inlining coverage to verify the
   call_file attribute attached to inlined routine DIEs. If function
   main.F is inlined into function main.G, we want to see that the
   call_file attribute in the inlined routine DIE for main.F is the
   same file as that reported for main.G.

 - fix a glitch with the way the DW_AT_decl_file attribute was
   being checked. The previous code relied on hard-coded indices
   into the line table files table, which is very brittle (since
   there is no requirement that files be ordered in any specific
   way). Instead, add machinery to look up the actual file string
   via the line table reader.

modload.MinReqs was passing modload.buildList to mvs.Reqs explicitly,
apparently as an optimization. However, we do not always have the
invariant that modload.buildList is complete: in particular, 'go mod
tidy' begins by reducing modload.buildList to only the set of modules
that provide packages to the build, which may be substantially smaller
than the final build list.

Other operations, such as 'go mod graph', do not load the entire
import graph, and therefore call Reqs with the unreduced build list.

Since Reqs retains modules according to a post-order traversal of the
list, an incomplete list may produce a different traversal order — and
therefore a different minimal solution, when multiple minimal
solutions exist. That caused 'go mod tidy' to produce different output
from other 'go' subcommands when certain patterns of dependencies are
present.

Since passing in the build list is only an optimization anyway, remove
the parameter and recompute the actual (complete) list at the
beginning of mvs.Reqs itself. That way, it is guaranteed to be
complete and in canonical order.

'go tool trace' pointed at an obvious inefficiency; roughly the first
fifth of the program's life was CPU-heavy and making use of only one CPU
core at a time.

This was due to genOp being run before genLower. We did make genLower
use goroutines to parallelize the work between architectures, but we
didn't make genOp run in parallel too.

Do that. To avoid having two layers of goroutines, simply fire off all
goroutines from the main function, and inline genLower, since it now
becomes just two lines of code.

Overall, this shaves another ~300ms from 'go run *.go' on my laptop.

This cleans up the isel code generation in ssa for ppc64x.

Current there is no isel op and the isel code is only
generated from pseudo ops in ppc64/ssa.go, and only using
operands with values 0 or 1. When the isel is generated,
there is always a load of 1 into the temp register before it.

This change implements the isel op so it can be used in PPC64.rules,
and can recognize operand values other than 0 or 1. This also
eliminates the forced load of 1, so it will be loaded only if
needed.

This will make the isel code generation consistent with other ops,
and allow future rule changes that can take advantage of having
a more general purpose isel rule.

When compiling expression switches, we try to optimize runs of
constants into binary searches. The ordering used isn't visible to the
application, so it's unimportant as long as we're consistent between
sorting and searching.

For strings, it's much cheaper to compare string lengths than strings
themselves, so instead of ordering strings by "si <= sj", we currently
order them by "len(si) < len(sj) || len(si) == len(sj) && si <= sj"
(i.e., the lexicographical ordering on the 2-tuple (len(s), s)).

However, it's also somewhat cheaper to compare strings for equality
(i.e., ==) than for ordering (i.e., <=). And if there were two or
three string constants of the same length in a switch statement, we
might unnecessarily emit ordering comparisons.

For example, given:

    switch s {
    case "", "1", "2", "3": // ordered by length then content
        goto L
    }

we currently compile this as:

    if len(s) < 1 || len(s) == 1 && s <= "1" {
        if s == "" { goto L }
        else if s == "1" { goto L }
    } else {
        if s == "2" { goto L }
        else if s == "3" { goto L }
    }

This CL switches to using a 2-level binary search---first on len(s),
then on s itself---so that string ordering comparisons are only needed
when there are 4 or more strings of the same length. (4 being the
cut-off for when using binary search is actually worthwhile.)

So the above switch instead now compiles to:

    if len(s) == 0 {
        if s == "" { goto L }
    } else if len(s) == 1 {
        if s == "1" { goto L }
        else if s == "2" { goto L }
        else if s == "3" { goto L }
    }

which is better optimized by walk and SSA. (Notably, because there are
only two distinct lengths and no more than three strings of any
particular length, this example ends up falling back to simply using
linear search.)

When emitting base cases, previously we would emit:

    if c2 { s2 }
    if c3 { s3 }

With this CL, we instead emit:

    if c1 { s1 }
    else if c2 { s2 }
    else if c3 { s3 }

Most of the time, this doesn't make a difference, because s1/s2/s3 are
typically "goto" statements. But for type switches, we currently emit:

    if hash == 271 { if _, ok := iface.(T1); ok { goto t1case } }
    if hash == 314 { if _, ok := iface.(T2); ok { goto t2case } }

That is, the if bodies can fallthrough, even though it's impossible
for them to match any of the subsequent cases.

Complete interfaces before comparing them with Checker.identical.
This requires passing through a *Checker to various functions that
didn't need this before.

Verified that none of the exported API entry points for interfaces
that rely on completed interfaces are used internally except for
Interface.Empty. Verified that interfaces are complete before
calling Empty on them, and added a dynamic check in the exported
functions.

Unfortunately, this fix exposed another problem with an esoteric
test case (#33656) which we need to reopen.

Fixes #34151.
Updates #33656.
