If one quickly looks at the strings package godoc, reading the name
TrimLeft, one might think it removes a prefix from the string.
The function's godoc does explain its purpose, but it's apparent that it
is not clear enough, as there have been numerous raised issues about
this confusion: #12771#14657#18160#19371#20085#25328#26119. These
questions are also frequent elsewhere on the internet.
Add a very short paragraph to the godoc, to hopefully point new Go
developers in the right direction faster. Do the same thing for
TrimRight and TrimSuffix.

Given a carefully constructed input, writebarrier would
split a block with the OpAddr in the first half and the
VarDef in the second half which ultimately leads to a
compiler crash because the scheduler is no longer able
to put them in the proper order.
To fix, recognize the implicit dependence of OpAddr on
the VarDef of the same symbol if any exists.
This fix was chosen over making OpAddr take a memory
operand to make the dependence explicit, because this
change is less invasive at this late part of the 1.11
release cycle.

Before CL 4281055 in 2011, the reflect package was quite different.
rtype, then called commonType, was embedded in exported structs with
names like StructType. In order to avoid accidental conversions
between pointers to these public structs, which sometimes had
identical fields, the embedded commonType fields were tagged.
In CL 4281055 the formerly public structs were unexported, and all
access was done through the Type interface. At that point the field
tags in the reflect structs were no longer useful.
In Go 1.8 the language was changed to ignore struct field tags when
converting between types. This made the field tags in the reflect
structs doubly useless.
This CL simply removes them.

The Server distinguishes "new" vs "idle" connections. A TCP connection
from which no bytes have yet been written is "new". A connection that
has previously served a request and is in "keep-alive" state while
waiting for a second or further request is "idle".
The graceful Server.Shutdown historically only shut down "idle"
connections, with the assumption that a "new" connection was about to
read its request and would then shut down on its own afterwards.
But apparently some clients spin up connections and don't end up using
them, so we have something that's "new" to us, but browsers or other
clients are treating as "idle" to them.
This CL tweaks our heuristic to treat a StateNew connection as
StateIdle if it's been stuck in StateNew for over 5 seconds.

On Wasm, the offset was not folded into LoweredAddr, so it was
not rematerializeable. This led to the address-taken operation
in some cases generated too early, before the local variable
becoming live. The liveness code thinks the variable live when
the address is taken, then backs it up to live at function
entry, then complains about it, because nothing other than
arguments should be live on entry.
This CL folds the offset into the address operation, so it is
rematerializeable and so generated right before use, after the
variable actually becomes live.
It might be possible to relax the liveness code not to think a
variable live when its address being taken, but until the address
actually being used. But it would be quite complicated. As we're
late in Go 1.11 freeze, it would be better not to do it. Also,
I think the address operation is rematerializeable now on all
architectures, so this is probably less necessary.
This may also be a slight optimization, as the address+offset is
now rematerializeable, which can be generated on the Wasm stack,
without using any "registers" which are emulated by local
variables on Wasm. I don't know how to do benchmarks on Wasm. At
least, cmd/go binary size shrinks 9K.
