These functions both use GEP_tup_like to get at the arguments bound to the
environment, but they were starting from a different 'level' of the
environment-box structure. Frighteningly, this was leading to them having
different opinions of how the bound arguments were aligned in some cases.

We can call take glue, rather than duplicating it inline.

Oops again.  Reverting a mistaken revert.

Oops.  This patch requires people to bump their LLVM version.

Bare functions will be represented as 'fn#' until they're implemented. Then
we'll switch it over to just 'fn'.

Issue #1022

Some code was relying on vectors being implicitly by-reference (as
non-immediate value). This adds the necessary &&-sigils.

Closes #1021

There's no good reason to force them to be spilled anymore. Some
pieces of trans become more elegant this way, and less stack allocs
and load/stores are needed.

Issue #1012

This way, it can be used to drop values without first spilling them.
