  -----------
  MemoryBuiltins: start using properties of functions

Prior to this change, we relied on the hard-coded list for all of the
information performed by MemoryBuiltins. With this change, we're able to
start relying on properites of functions described in attributes, which
opens the door to out-of-tree compilers being able to describe their
allocator functions to LLVM's optimizer logic without having to register
their implementation details with LLVM.

  Log Message:
  -----------
  MemoryBuiltins: accept non-TLI funcs with attribs as allocator funcs

This allows us to accept annotations from out-of-tree languages (the
example test is derived from Rust) so they can enjoy the benefits of
LLVM's optimizations without requiring LLVM to have language-specific
knowledge.

  Log Message:
  -----------
  BuildLibCalls: move inference of freeing memory later

This probably should have been part of D123089, but the effects of it
don't show up until we start removing functions from the table in
D130107. Oops.
