af7c9a42c1 syscall: implement getwd on Solaris
In support of the changes required for #8609, it was suggested that
syscall.getwd() be updated to work on Solaris first since the runtime
uses it and today it's unimplemented.

Fixes #12507

1ca7a64a0d cmd/compile/internal/gc: handle weird map literals in key dedup
We compute whether two keys k1 and k2 in a map literal are duplicates by
constructing the expression OEQ(k1, k2) and calling the constant
expression evaluator on that expression, then extracting the boolean
result.

Unfortunately, the constant expression evaluator can fail for various
reasons.  I'm not really sure why it is dying in the case of 12536, but
to be safe we should use the result only if we get a constant back (if
we get a constant back, it must be boolean).  This probably isn't a
permanent fix, but it should be good enough for 1.5.2.

A permanent fix would be to ensure that the constant expression
evaluator can always work for map literal keys, and if not the compiler
should generate an error saying that the key isn't a constant (or isn't
comparable to some specific other key).

This patch has the effect of allowing the map literal to compile when
constant eval of the OEQ fails.  If the keys are really equal (which the
map impl will notice at runtime), one will overwrite the other in the
resulting map.  Not great, but better than a compiler crash.

Fixes #12536

e6ee26a03b text/template: provide a way to trim leading and trailing space between actions
Borrowing a suggestion from the issue listed below, we modify the lexer to
trim spaces at the beginning (end) of a block of text if the action immediately
before (after) is marked with a minus sign. To avoid parsing/lexing ambiguity,
we require an ASCII space between the minus sign and the rest of the action.
Thus:

	{{23 -}}
	<
	{{- 45}}

produces the output
	23<45

All the work is done in the lexer. The modification is invisible to the parser
or any outside package (except I guess for noticing some gaps in the input
if one tracks error positions). Thus it slips in without worry in text/template
and html/template both.

Fixes long-requested issue #9969.

63e2bed0ab cmd/asm: fix another infinite loop in register list parser
The code parsing register lists involves an inner loop on
each range defined by the lo,hi bounds. The condition on
this loop (for lo<=hi) is fragile, because the bounds
are unsigned 16 bits numbers.

In some corner cases, the calculated upper bound is 2^16-1
leading to an infinite loop.

Parsing operand `[):[o-FP` results in:
- an infinite loop for non ARM architectures
- the generation of almost 2^16 errors for the ARM architecture
  (which are then ignored)

This CL improves the code in 3 ways:
- bail out early when parsing non R prefixed registers
- make sure the register index is never negative
- make sure the number of iterations is limited by the
  maximum size of the range (as a defensive measure).

Fixes #12469

5a3ff6c895 net: Make Listen(":port") use IPv6 when IPv4 is not supported.
When running an experimental kernel with IPv4 disabled, Listen(":port")
currently tries to create an AF_INET socket, and fails.  Instead, it
should see !supportsIPv4, and use an AF_INET6 socket.

This sort of environment is quite esoteric at the moment, but I can
force the tests to fail on regular Linux using the following tweaks:

- net/net.go: supportsIPv4, supportsIPv6, supportsIPv4map = false, true, false
- net/sockopt_linux.go: ipv6only=true
- net/ipsock_posix.go: Revert this fix
- ./make.bash && ../bin/go test net

Also, make the arrows in server_test.go point to the left, because
server<-client is easier to read.

Fixes #12510

703bd83623 cmd/compile: use []*Node instead of NodeList in sinit
This is a first of a set of changes to make the transition away from NodeList
easier by removing cases in which NodeList doesn't act semi-trivially like a
[]*Node.

This CL was originally prepared by Josh Bleecher Snyder <josharian@gmail.com>.

This change passes go build -toolexec 'toolstash -cmp' -a std.

4f74de1e4d cmd/go: fix Go buildid reading on Solaris
TestNoteReading fails on Solaris with linkmode=external due to some
assumptions made about how ELF .note sections are written by some
linkers.

On current versions of Solaris and older derivatives, SHF_ALLOC is
intentionally ignored for .note sections unless the .note section is
assigned to the text segment via a mapfile.  Also, if .note sections
are assigned to the text segment, no PT_NOTE program header will be
created thwarting Go's attempts at attempting to quickly find the
.note.

Furthermore, Go assumes that the relevant note segment will be placed
early in the file while the Solaris linker currently places the note
segment last in the file, additionally thwarting Go's optimisation
attempts that read only the first 16KB of the file to find the
buildid.

The fix is to detect when the note section is outside of the first
16KB of the file and then fallback to additionally reading that
section of the file.  This way, in future versions of Solaris when
this linking behaviour is changed, the fast path will always succeed
and we'll only be slower if it fails; likewise, any other linker that
does this will also just work.

Fixes #12178

6fd82d83d6 net/http: optimize some io.Copy calls by reusing buffers
Optimize two calls of io.Copy which cannot make use of neither
io.ReaderFrom nor io.WriterTo optimization tricks by replacing them with
io.CopyBuffer with reusable buffers.

First is fallback call to io.Copy when server misses the optimized case
of using sendfile to copy from a regular file to net.TCPConn; second is
use of io.Copy on piped reader/writer when handler implementation uses
http.CloseNotifier interface. One of the notable users of
http.CloseNotifier is httputil.ReverseProxy.
