On Windows 7 (and below), console handles are not real kernel handles
but are rather userspace objects, with information passed via special
bits in the handle itself. That means they can't be passed in
PROC_THREAD_ATTRIBUTE_HANDLE_LIST, even though they can be inherited.
So, we filter the list passed to PROC_THREAD_ATTRIBUTE_HANDLE_LIST to
not have any console handles on Windows 7. At the same time, it turns
out that the presence of a NULL handle in the list is enough to render
PROC_THREAD_ATTRIBUTE_HANDLE_LIST completely useless, so filter these
out too. Console handles also can't be duplicated into parent processes,
as inhertance always happens from the present process, so duplicate
always into the present process even when a parent process is specified.

This ir.Dump call is a debugging artifact introduced in
golang.org/cl/274103, which should never be printed for valid,
non-generic code, but evidently can now sometimes appear due to how
the parser handles invalid syntax.
The parser should probably not recognize "x[2]" as a type expression
in non-generics mode, but also probably we shouldn't try noding after
reporting syntax errors. Either way, this diagnostic has outlived its
usefulness, and noder's days are numbered anyway, so we might as well
just remove it to save end users any confusion.

When 'go get' updates a module, it may update another module in the
build list that provides a package in 'all' that wasn't loaded as part
of the 'go get' command. If 'go get' doesn't add a sum for that
module, builds may fail later.
With this change, 'go get' will fetch a sum for the content of an
updated module if we had a sum for the version before the update.
'go get' won't load the complete package graph, so there are still
cases where the build may be broken, like when an updated (but not
loaded) package imports a package from a new module.

module path in order to validate arguments. LoadModFile may write
go.mod and go.sum to fix formatting and add a go directive. This calls
keepSums, which, in eager mode, loaded the complete module graph in
order to find out what sums are needed to load the complete module
graph. If go.mod requires a lower version of a module than will be
selected later, keepSums causes the sum for that version's go.mod to
be retained, even though it isn't needed later after a consistent
go.mod is written.
This CL fixes keepSums not to load the graph if it hasn't already been
loaded (whether eager or lazy), addressing comments from CL 318629.

During DWARF debug location generation, as a preamble to the main data
flow analysis, examine the function entry block to look for in-params
arriving in registers that are partially or completely dead, and
insert new OpArg{Int,Float}Reg values for the dead or partially-dead
pieces. In addition, add entries to the f.NamedValues table for
incoming live register-resident params that don't already have
entries. This helps create better/saner DWARF location expressions for
params. Example:
func foo(s string, used int, notused int) int {
return len(s) + used
}
When optimization is complete for this function, the parameter
"notused" is completely dead, meaning that there is no entry for it in
the f.NamedValues table (which then means we don't emit a DWARF
variable location expression for it in the function enty block). In
addition, since only the length field of "s" is used, there is no
DWARF location expression for the other component of "s", leading to
degraded DWARF.
There are still problems/issues with DWARF location generation, but
this does improve things with respect to being able to print the
values of incoming parameters when stopped in the debugger at the
entry point of a function (when optimization is enabled).

Instead, check that stale packages in the standard library
are not rebuilt when already present in the build cache,
and are not installed implicitly when rebuilt.
We retain the staleness checks for the runtime package in tests
involving '-i', because those are guaranteed to fail anyway if the
package is stale and the "stale" failure message is arguably clearer.
They can be removed if/when we remove the '-i' flag, but the runtime
package is less likely to become stale because it does not have cgo
