Top-level functions in the net package that only read files,
for example LookupPort(...), or LookupIP(host) where host resides
in /etc/hosts, now work on wasip1.
If the application has the ability to create sockets (for example,
when using a sockets extension to WASI preview 1), it's now
possible to do name resolution by passing a custom Dial function
to a Resolver instance.

There are currently no examples in the new slices and maps package, so
add some. This adds examples for most functions in the slices package
except the very obvious ones, and adds examples for the DeleteFunc and
EqualFunc functions in the maps package.
Also clarify/correct a few doc comments:
* EqualFunc takes an "equality" function, not a "comparison" function
* It's confusing for Delete and DeleteFunc to say they "do not create a
new slice", as they do return a new slice. They already say they
"return the modified slice" which is enough.
* Similar for Compact, and mention that it returns the modified slice
(and say why)
* Note that CompactFunc keeps the first element in equal runs
* Say what cmp is in SortStableFunc and IsSortedFunc
* Say that MinFunc and MaxFunc return the first value

The large-function phi placement algorithm evidently doesn't like the
same pseudo-variable being used to represent expressions of varying
types.
Instead, use the same tactic as used for "valVar" (ssa.go:6585--6587),
which is to just generate a fresh marker node each time.
Maybe we could just use the OMIN/OMAX nodes themselves as the key
(like we do for OANDAND/OOROR), but that just seems needlessly risky
for negligible memory savings. Using fresh marker values each time
seems obviously safe by comparison.

Our large-function phi placement algorithm is incompatible with phi
opcodes already existing in the SSA representation. Instead, use simple
variable assignments and have the phi placement algorithm place the phis
we need for min/max.
Turns out the small-function phi placement algorithm doesn't have this
sensitivity, so this bug only occurs in large functions (>500 basic blocks).
Maybe we should document/check that no phis are present when we start
phi placement (regardless of size). Leaving for a potential separate CL.
We should probably also fix the placement algorithm to handle existing
phis correctly. But this CL is probably a lot smaller/safer than
messing with phi placement.

Running go test -parallel=1 -v, these are the top 10 tests:
PASS: TestScript/mod_invalid_version 40.14s
PASS: TestScript/build_cache_output 46.82s
PASS: TestScript/get_legacy 48.69s
PASS: TestTestCache 58.44s
PASS: TestScript/mod_get_direct 62.88s
PASS: TestScript/build_pgo_auto_multi 63.49s
PASS: TestScript/build_pgo_auto 70.69s
PASS: TestScript/gcflags_patterns 95.17s
PASS: TestScript/mod_list_compiled_concurrent 124.31s
PASS: TestScript/vet_flags 202.85s
Change the top 5 not to run builds at all, so they don't
have to use -a or clear the go build cache.
mod_get_direct should be replaced with a vcs-test test.
mod_invalid_version should be replaced with a vcs-test test.
get_legacy should be deleted eventually.
