Russ Cox c2dd33a46f cmd/ld: clear unused ctxt before morestack
For non-closure functions, the context register is uninitialized
on entry and will not be used, but morestack saves it and then the
garbage collector treats it as live. This can be a source of memory
leaks if the context register points at otherwise dead memory.
Avoid this by introducing a parallel set of morestack functions
that clear the context register, and use those for the non-closure functions.

I hope this will help with some of the finalizer flakiness, but it probably won't.

Fixes #7244.

The header files under this directory are strictly internal to the gc
toolchain, so please don't copy them to the system include file
directory (/usr/include, /usr/local/include, etc.)

Also note that they must be kept as is in $GOROOT/include, or cmd/dist
will malfunction.
