    This is a port of https://golang.org/cl/18150 to the gccgo runtime.
    
    The previous behaviour of installing the signal handlers in a separate
    thread meant that Go initialization raced with non-Go initialization if
    the non-Go initialization also wanted to install signal handlers.  Make
    installing signal handlers synchronous so that the process-wide behavior
    is predictable.

PR64682 is a problem in distribute_notes, where it has trouble putting
a REG_DEAD note for a reg that is set twice in the right spot.  My fix
for that did the wrong thing for PR69567.  And then my attempted fix
for that one made PR64682 fail again.

Instead, let's just lose the note in such complicated cases, like we
already do in certain similar cases.
