This commit adds scripts for running the WebAssembly binaries that the
Go compiler will produce.
The script go_js_wasm_exec uses Node.js to run the binaries. Adding it
to PATH will enable "go run" and "go test" to work for js/wasm
without having to manually provide the -exec flag.
See https://golang.org/cmd/go/#hdr-Compile_and_run_Go_program
for more information.
The web page wasm_exec.html is an example on how to run the same
binaries in a web browser.
Both scripts use wasm_exec.js as a shared library.

There is currently no way for os.FileMode.IsRegular to report false
without being one of the following types:
ModeDir | ModeSymlink | ModeNamedPipe | ModeSocket | ModeDevice
This makes it difficult for custom implementations of os.FileInfo to return
a Mode that is explicitly not regular without resorting to setting one
of the types listed above. However, every one of the aforementioned types
are ill-suited as a general-purpose "not regular" file type.
Thus, add a ModeIrregular to serve exactly for that purpose.
The ModeIrregular type carries no information other than the fact that the
file is not regular.

Preserve the original behaviour of \s.
Prior to Perl 5.18, \s did not match vertical tab. Bake that into
make_perl_groups.pl as an override so that perl_groups.cc retains
its current definitions when rebuilt with newer versions of Perl.
This fixes make_perl_groups.pl to generate an unchanged perl_groups.go

When snapshotting the execution time stats of a goroutine
we take into account the intermediate values kepts in the GDesc's
gdesc field. At the end of goroutine analysis, we go through all
goroutines and replace the GExecutionStat with the new snapshot.
Here the mistake was that we replaced the GExecutionStat with
the value that reflects the intermediate values, but did clear
the intermediate values. So, when the following finalizeActiveSpans
runs, it trieds to add the intermediate values again (double-counting)
when taking a snapshot.
Fix the issue by using the finalized GExecutionStat instead of
recomputing the snapshot. While we are here, refactor the finalization
logic so it can be used when processing GoEnd, GoStop events.

to
real 0m0.237s
user 0m0.180s

This will make it reasonable to add more constants to the test.
I am also hopeful that it might help a bit with intermittent
cmd/compile/internal/gc test timeouts on the build dashboard
on the slower builders.
The time savings are entirely in compilation time,
by avoiding generating one giant func main.
Instead, generate tables of tests to be run,
which are translated into static data,
and then loop over those tests.
While we're here, do some minor cleanup:
* Remove the _ssa suffix on function names,
as that was only needed during ssa bootstrapping.
* Clean up error handling during test generation.
* Make functions single-line, to reduce future diff sizes.
Diffing giant files is slow.

In expandmeth, we call expand1/expand0 to build a list of all
candidate methods to promote, and then we use dotpath to prune down
which names actually resolve to a promoted method and how.
However, previously we still computed "followsptr" based on the
expand1/expand0 traversal (which is depth-first), rather than
dotpath (which is breadth-first). The result is that we could
sometimes end up miscomputing whether a particular promoted method
involves a pointer traversal, which could result in bad code
generation for method trampolines.
