Try to set stdio to non-blocking mode before the os package
calls NewFile for each fd. NewFile queries the non-blocking flag
but doesn't change it, even if the runtime supports non-blocking
stdio. Since WebAssembly modules are single-threaded, blocking
system calls temporarily halt execution of the module. If the
runtime supports non-blocking stdio, the Go runtime is able to
use the WASI net poller to poll for read/write readiness and is
able to schedule goroutines while waiting.

When unification of two types succeeds and at least one of them
is an interface, we must be more cautious about when to accept
the unification, to avoid order dependencies and unexpected
inference results.
The changes are localized and only affect matching against
interfaces; they further restrict what are valid unifications
(rather than allowing more code to pass). We may be able to
remove some of the restriotions in a future release.
See comments in code for a detailed description of the changes.
Also, factored out "asInterface" functionality into a function
to avoid needless repetition in the code.

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.

When reusing a g struct the runtime did not reset
g.raceignore. Initialize raceignore to zero when initially
setting racectx.
A goroutine can end with a non-zero raceignore if it exits
after calling runtime.RaceDisable without a matching
runtime.RaceEnable. If that goroutine's g is later reused
the race detector is in a weird state: the underlying
g.racectx is active, yet g.raceignore is non-zero, and
raceacquire/racerelease which check g.raceignore become
no-ops. This causes the race detector to report races when
there are none.

We do not index std as a whole module ever.
When working in the main Go repo, files in package change often,
so we don't want to pay the cost of reindexing all of std when what
we really need is just to reindex strings. Per-package indexing
works better for that case.
When using a released Go toolchain, we don't have to worry about
the whole module changing, but if we switch to whole-module indexing
at that point, we have the potential for bugs that only happen in
released toolchains. Probably not worth the risk.
For similar reasons, we don't index the current work module as
a whole module (individual packages are changing), so we use the heuristic
that we only do whole-module indexing in the module cache.
The new toolchain modules live in the module cache, though, and
our heuristic was causing whole-module indexing for them.
As predicted, enabling whole-module indexing for std when it's
completely untested does in fact lead to bugs (a very minor one).
This CL turns off whole-module indexing for std even when it is
in the module cache, to bring toolchain module behavior back in
line with the other ways to run toolchains.
