compiler.cfg.linear-scan.allocation.*: maybe a fix for #1227
...
The register allocator pops from the unhandled-intervals and
unhandled-sync-points heaps. If two live intervals share the same
start slot, then they can be popped in either order leading to
differently generated code. So instead use one
heap (unhandled-min-heap) and both the start and end slot as the heap
key to resolve tie-breakers

compiler.cfg.linear-scan now supports partial sync-points where all registers are spilled; taking advantage of this, there are new trigonometric intrinsics which yield a 2x performance boost on benchmark.struct-arrays and a 25% boost on benchmark.partial-sums

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

If a register is spilled and the reload location is also a copy, we chicken out and don't coalesce. This is suboptimal but it's not clear to me how to implement it cleanly, and SSA graph coloring will solve this problem eventually anyway
