Merge FUN_STATIC closure with its SRT
Summary: The idea here is to save a little code size and some work in the GC, by collapsing FUN_STATIC closures and their SRTs. This is (4) in a series; see D4632 for more details. There's a tradeoff here: more complexity in the compiler in exchange for a modest code size reduction (probably around 0.5%). Results: * GHC binary itself (statically linked) is 1% smaller * -0.2% binary sizes in nofib (-0.5% module sizes) Full nofib results comparing D4634 with this: P177 (ignore runtimes, these aren't stable on my laptop) Test Plan: validate, nofib Reviewers: bgamari, niteria, simonpj, erikd Subscribers: thomie, carter Differential Revision: https://phabricator.haskell.org/D4637
