0c012af114 cmd/go: kill test.out after 1 minute
Will have to do better but this is enough to
stop the builders from hanging, I hope.

1250f94f93 runtime: runtime.usleep() bugfix on darwin/amd64 and linux/arm
pkg/runtime/sys_darwin_amd64.s: fixes syscall select nr
pkg/runtime/sys_linux_arm.s: uses newselect instead of the now unimplemented
        (old) select, also fixes the wrong div/mod statements in runtime.usleep.
Fixes #2633

415f15b667 image: rename image.Tiled to image.Repeated.
What package image currently provides is a larger image consisting
of many copies of a smaller image.

More generally, a tiled image could be a quilt consisting of different
smaller images (like Google Maps), or a technique to view a portion of
enormous images without requiring the whole thing in memory.

This richer construct might not ever belong in the standard library (and
is definitely out of scope for Go 1), but I would like the option for
image.Tiled to be its name.

97fd7d5f34 gc: inlining fixes
flag -l means: inlining on, -ll inline with early typecheck
-l lazily typechecks imports on use and re-export, nicer for debugging
-lm produces output suitable for errchk tests, repeated -mm... increases inl.c's verbosity
export processed constants, instead of originals
outparams get ->inlvar too, and initialized to zero
fix shared rlist bug, that lead to typecheck messing up the patched tree
properly handle non-method calls to methods T.meth(t, a...)
removed embryonic code to handle closures in inlined bodies
also inline calls inside closures (todo: move from phase 6b to 4)

Fixes #2579.

b4be65bc7f math/big: simplify fast string conversion
- use slice ops for convertWords instead of lo/hi boundaries
- always compute leading zeroes (simplifies logic significantly),
  but remove them once, at the end (since leafSize is small, the
  worst-case scenario is not adding significant overhead)
- various comment cleanups (specifically, replaced direct -> iterative,
  and indirect -> recursive)
- slightly faster overall for -bench=String

70ed0ac588 go-mode.el: fix syntax highlighting of backticks
Instead of syntax-tables, an extended go-mode-cs is used for
from a font-lock callback.

Cache invalidation must happen in a before-change-function
because font-lock runs in an after-change-function, potentially
before the cache invalidation takes place.

Performance is reasonable, even with src/pkg/html/entity.go
and test/fixedbugs/bug257.go.

Fixes #2330.
