Subject: Merge of branch linear-typing:

1) Revised division of labor between RTLtyping and Lineartyping:
- RTLtyping no longer keeps track of single-precision floats,
  switches from subtype-based inference to unification-based inference.
- Unityping: new library for unification-based inference.
- Locations: don't normalize at assignment in a stack slot
- Allocation, Allocproof: simplify accordingly.
- Lineartyping: add inference of locations that contain
  a single-precision float.
- Stackingproof: adapted accordingly.

This addresses a defect report whereas RTLtyping was rejecting code that used a RTL pseudoreg to hold both double- and single-precision floats (see test/regression/singlefloats.c).

This corresponds to commits 2435+2436 plus improvements in Lineartyping.

2) Add -dtimings option to measure compilation times.
Moved call to C parser from Elab to Parse, to make it easier to
measure parsing time independently of elaboration time.
