compiler.cfg.linear-scan.allocation.splitting: better def for split-uses
...
it seems to be just as fast as the wordier one

compiler.cfg.linear-scan.ranges: remove the live-range definition and
...
use integer pairs instead
so instead of ranges being a sequence of live-ranges it is now a
sequence of integer pairs instead. That makes the
compiler.cfg.linear-scan.ranges simpler and easier to generalize

compiler.cfg: convert code into two-operand form before SSA destruction; SSA destruction now operates on a relaxed SSA form where multiple defs of the same vreg are allowed, but only within a single basic block. This makes linear scan's coalescing redundant, allowing it to be removed completely

compiler.cfg.linear-scan: fix case where a register can be made available for only a part of a live interval's lifetime, but there are no more usages after the split location. This case never came up until global stack analysis, at which point it started to be exercised on x86-32

compiler.cfg.linear-scan: Re-implement spilling, add some additional runtime assertions, simplify assignment pass since it doesn't have to track spill slots anymore; just assume a live value that's not in active or inactive is spilled

inactive splitting: if all inactive intervals' registers are in use, don't fail
fix stack analysis tests
