In preparation for being able to run a go program that has code
in several objects, this changes from having several linker
symbols used by the runtime into having one linker symbol that
points at a structure containing the needed data. Multiple
object support will construct a linked list of such structures.
A follow up will initialize the slices in the themoduledata
structure directly from the linker but I was aiming for a minimal
diff for now.

There is currently no way to ignore signals using the os/signal package.
It is possible to catch a signal and do nothing but this is not the same
as ignoring it. The new function Ignore allows a set of signals to be
ignored. The new function Reset allows the initial handlers for a set of
signals to be restored.
Fixes#5572

This CL introduces new methods for 'context' type, so we can
manipulate its values in an architecture independent way.
Use new methods to replace both 386 and amd64 versions of
dosigprof with single piece of code.
There is more similar code to be converted in the following CLs.
Also remove os_windows_386.go and os_windows_amd64.go. These
contain unused functions.
