The struct RawSockaddr contains a field Data which
should be uint8 on ppc64 and ppc64le, but is declared
as int8 in gccgo. This change adds a two new files
which contain the structure declaration for
RawSockaddr, one with the correct types for for ppc64
and ppc64le, and the other for non-ppc64 platforms.

There is no need to make type descriptors for named types when there
are errors during package compilation. Particularly, if the error in
package compilation is from a malformed named type, there is no
guarantee a type descriptor can be created.

This change modifies the "gotest" shell script
to kill all processes, including "sleep", spawned
by the timeout subshell. This prevents the sleep
process from living beyond the gotest process.
BACKGROUND
The "gotest" shell script spawns "sleep" processes
in the background to kill off test cases that run
past their specified timeout. There are commands
included that appear to kill the sleep process,
but they only kill the parent shell, causing the
sleep process to reparent.
The orphaned sleep process can cause issues when
gotest is run under some build systems, such as
Ninja [0]. The particular issue with Ninja is the
method it uses to identify terminated processes:
it creates a pipe, passes the write end to the
child process, and waits for EOF. In the case of
libgo/gotest, the orphaned sleep process inherits
the pipe FD and keeps it open for 4 minutes by
default.

Errors reported from malformed builtin calls are handled in a later
pass than the one in which they are detected. If a malformed builtin
call is lowered into an error expression too early, these errors will
never be reported.
Fixes golang/go#11561.

Function declarations don't create a block where the variables listed
in the parameter list are declared. Because there are no variables
declared, the types of the parameter variables is unchecked, allowing
for invalid values to be used as the type. This patch adds a special
case to the check_types pass for function declarations.
Fixes golang/go#11567.

"built-in functions do not have standard Go types, so they can only
appear in call expressions; they cannot be used as function values."
Fixes golang/go#11570.
