ea08952aa2 cmd/internal/obj/loong64: add support for instructions BSTRPICK.{W/D} and BSTRINS.{W/D}
Go asm syntax:
	BSTRPICK{W/V}	$msb, RJ, $lsb, RD
	BSTRINS{W/V}	$msb, RJ, $lsb, RD

Equivalent platform assembler syntax:
	bstrpick.{w/d}	rd, rj, $msb, $lsb
	bstrins.{w/d}	rd, rj, $msb, $lsb

10ed134afe os: improve Windows fixLongPath
CL 574695 added caching the os.Chdir argument for Windows, and used the
cached value to assess the length of the current working directory in
addExtendedPrefix (used by fixLongPath).

It did not take into account that Chdir can accept relative paths, and
thus the pathLength calculation in addExtendedPrefix can be wrong.

Let's only cache the os.Chdir argument if it's absolute, and clean the
cache otherwise, thus improving the correctness of fixLongPath.

For #41734
For #21782
For #36375

422f4705ca cmd/dist: set go version in bootstrap go.mod file
The commands to build the bootstrap toolchains and go commands are run
from modules created by two bootstrap go.mod files: one is used when
building toolchain1 and go_bootstrap, and the other is used for
toolchain2 and toolchain3, and the final build. Currently the first has
a go directive specifying go 1.20, and the second one does not have a go
directive at all. This affects the default GODEBUG setting when building
the final toolchain: the default GODEBUG value is based on the go
version of the go.mod file, and when the go.mod file does not have a
version it defaults to go1.16. We should set the go directive on the
bootstrap used for the second half of the builds to use the current go
verison from the std's go.mod file (which is the same as the version on
cmd's go.mod file).

The go.mod file used for the initial bootstrap should have a go
directive with the minimum version of the toolchain required for
bootstrapping. That version is the current version - 2 rounded down to
an even number.

For #64751
Fixes #68797

c7faf7f514 runtime: fix nanotime1 on windows/arm
nanotime1 is broken on windows/arm since CL 526358, which
unintentionally removed a necessary instruction. It hasn't been
noticed till now because the there is no windows/arm builder.

This CL restores the instruction.

Fixes #68996.

1a7a85359e cmd/compile/internal/ssagen: add initial test coverage for intrinsics
Add basic test coverage for the intrinisic table - this at least allows
us to tell if intrinsics are added or removed unexpectedly. Code
generation changes resulting from intrinsics is not covered and is
left for test/codegen and others.

4a9d98d49a syscall: optimize Getwd on aix
When looking for \0, use clen which may be optimized.

Also, return EINVAL when returned string is empty.

This makes it similar to how it is implemented in *bsd and solaris.

854349eeb4 os/user: speed up Current on Windows
[This is a roll-forward of CL 597255, which had to be rolled back
because it broke the windows-arm64 builder, whose current user display
name is unavailable. This new CL fixes the issue by reintroducing the
historical behavior of falling back to the user name instead of
returning an error].

user.Current is slow on Windows sessions connected to an Active
Directory domain. This is because it uses Windows APIs that do RPC
calls to the domain controller, such as TranslateAccountW and
NetUserGetInfo.

This change speeds up user.Current by using the GetUserNameEx API
instead, which is already optimized for retrieving the current user
name in different formats.

These are the improvements I see with the new implementation:

755c18ecdf unique: use TypeFor instead of TypeOf to get type in Make
Currently the first thing Make does it get the abi.Type of its argument,
and uses abi.TypeOf to do it. However, this has a problem for interface
types, since the type of the value stored in the interface value will
bleed through. This is a classic reflection mistake.

Fix this by implementing and using a generic TypeFor which matches
reflect.TypeFor. This gets the type of the type parameter, which is far
less ambiguous and error-prone.

Fixes #68990.

This is a building block so that tests can be written for exported
type parameterized aliases (like reproducing #68526).

This also adds a test that uses this feature. A type parameterized
alias is used so aliastypeparams and gotypesalias must be enabled.
gotypesalias is enabled by the go module version. The alias is not
exported and will not appear in exportdata. The test shows the
package containing the alias can be imported. This encapsulates
the level of support of type parameterized aliases in 1.23.

1a90dcdaaf go/types, types2: unalias tilde terms in underIs
Unalias the ~T terms during underIs. Before, if T was an alias
of U, it may pass T to the iteration function. The iterator
function expects an underlying type, under(U), to be passed.
This caused several bugs where underIs is used without
eventually taking the underlying type.

Updates #68935
Fixes #68903

c6c9634515 cmd/compile/internal/ssagen: factor out intrinsics code
The intrinsic handling code is a good thousand lines in the fairly
large ssa.go file. This code is already reasonably self-contained - factor
it out into a separate file so that future changes are easier to manage
(and it becomes easier to add/change intrinsics for an architecture).

b6f05cc333 cmd/compile/internal/ssagen: improve intrinsic architecture handling
The architecture handling code for intrinsics is more complex than
it needs to be. sys.Archs is already an array of *sys.Arch and the
existing InFamily function can be used instead of a reimplementation.

Add some test coverage for sys.Arch.InFamily while here.

d49d0e0d3a runtime: on AIX, fix call to _cgo_sys_thread_create in _rt0_ppc64_aix_lib
The AIX ABI requires allocating parameter save space when calling
a function, even if the arguments are passed via registers.

gcc sometimes uses this space. In the case of the cgo c-archive
tests, it clobbered the storage space of argc/argv which prevented
the test program from running the expected test.

Fixes #68957
