11f6cc96bf Delete MethodBodies that only filtered reserved registers.
The register allocators know to filter reserved registers from the allocation
orders, so we don't need all of this boilerplate.

07cbe23173 Assorted fixes for Win64 EH unwind info emission:
- Flip order of bitfields. This gets our output matching GAS.
- Handle case where the end of the prolog wasn't specified.
- If the resulting unwind info struct is less than 8 bytes, pad to 8 bytes.

Add a test for the latter two.

4eeb7b662b My attempt at fixing the leak reported by the valgrind buildbots. Valgrind will
still report leaks, but they're spurious now. Valgrind cannot peer into

know how big the array is.

ca93138e11 Test .seh_startchained and .seh_endchained parsing.
Rework how the MCWin64EHUnwindInfo instances are stored. Fix issues with
chained unwind areas exposed by the test that were related to this.

The ChainedParent field had the wrong address, because when the chained unwind
info was added, the addresses shifted around. Now we store the pointers to the
structures, which are now allocated from the MC heap.

b8d936bc17 Add a RAGreedy::canEvict function.
This doesn't change functionality (much), but it allows for a more fine-grained
eviction policy. The current policy only compares spill weights, and that is not
always the best thing to do.  Spill weights are designed to serve linear scan,
and they don't consider live range splitting.

Add a mechanism so canEvict() can request that a live range be evicted and
split/spilled. This is to avoid infinite eviction loops.

76927d7303 Rewrite fast-isel integer cast handling to handle more cases, and to be simpler and more consistent.
The practical effects here are that x86-64 fast-isel can now handle trunc from i8 to i1, and ARM fast-isel can handle many more constructs involving integers narrower than 32 bits (including loads, stores, and many integer casts).
