1407846656 docs: update SIL-Utilities.md 
And move it out of the "proposals" folder, directly into "docs". It's now more a documentation of what we have and useful as a programming guide.

5baf2af88a [sil] Add a new instruction called explicit_copy_addr. 
This is exactly like copy_addr except that it is not viewed from the verifiers
perspective as an "invalid" copy of a move only value. It is intended to be used
in two contexts:

1. When the move checker emits a diagnostic since it could not eliminate a copy,
we still need to produce valid SIL without copy_addr on move only types since we
will hit canonical SIL eventually even if we don't actually codegen the SIL. The
pass can just convert said copy_addr to explicit_copy_addr and everyone is
happy.

2. To implement the explicit copy function for address only types.

82ae1d1a2d [SIL.rst] Cleanup docs on explicit_copy_value. 
There really isn't a point in repeating the verbage from copy_value. So I
removed that and just referred back to the copy_value documentation and focused
instead on what makes explicit_copy_value different semantically from
copy_value, how it is used to work around the invariant in Canonical SIL that
move only typed values can not be copied. This is useful for:

1. Implementing an explicit copy for no implicit copy types.

2. When the move checker errors since it can't produce a move only solution for
a value, we change all of the copies into explicit_copy_value. We need some sort
of copy to ensure later once we are in Canonical SIL, Ownership SSA is correct
/and/ we maintain the no copy of move only typed values in Canonical SIL.

4a81bcafe4 [SIL.rst] Add to copy_value's docs that in non-Raw SIL, one cannot give copy_value a move only value as an operand. 
I am enforcing this in the verifier, so it makes sense to document in SIL.rst.

Michael Gottesman
3bdfa239ca [SIL.rst] Add docs explaining how Move Only Types can be copied in Raw SIL, but not in later SIL stages. 
Since I am going to start enforcing this invariant more broadly, I want to
document it in SIL.rst. I also included a discussion explaining why we maintain
this invariant: it enables SILGen to use a simple algorithm to insert copies/us
to clean that up using a diagnostic guaranteed optimization pass which runs on
Raw SIL.

for the linker. Move it back to a driver option and hide both it and the
stdlib flag from help.
