inefficient file system buffering if the writes are not a multiple of the desired
buffer size. Avoid this by limiting the large write to a multiple of the buffer
size and copying the remainder into the buffer.
Thanks to Dan for pointing this out.

Initially, slot indexes are quad-spaced. There is room for inserting up to 3
new instructions between the original instructions.
When we run out of indexes between two instructions, renumber locally using
double-spaced indexes. The original quad-spacing means that we catch up quickly,
and we only have to renumber a handful of instructions to get a monotonic
sequence. This is much faster than renumbering the whole function as we did
before.

instruction.
You can't really predict how many indexes will be needed from the number of
defs, so let's keep it simple.
Also remove an extra empty index that was inserted after each basic block. It
was intended for live-out ranges, but it was never used that way.

This caps the number of write(2) calls per string to a maximum of 2.

correct
type after type legalization has completed. Before then it may simply not be big
enough to hold the shift amount, particularly on x86 which uses a very small type
for shifts (this issue broke stuff in the past which is why LegalizeTypes carefully
uses a large type for shift amounts).

There was a previous implementation with patterns that would
have matched e.g.
shl <v4i32> <i32>,
but this is not valid LLVM IR so they never were selected.

"icmp pred %X, CI" and a number of examples where "%X = binop %Y, CI2".
Some of these cases (div and rem) used to make it through opt -O2, but the
others are probably now making code elsewhere redundant (probably instcombine).

it. It's been assumed up til now that it would be in its immediate
successor. However, this isn't necessarily the case. It could be in one of its
successor's successors.
Modify the code to more thoroughly check for an 'eh.selector' call in
successors. It only looks at a successor if we get there as a result of an
unconditional branch.
Testcase ObjC/exceptions-4.m in r126968.

There are probably much larger speedups to be had by renumbering locally instead
of looping over the whole function. For now, the greedy register allocator is
25% faster.

This is much faster than using a pointer to a ManagedStatic object accessed with
a function call. The greedy register allocator is 5% faster overall just from
the SlotIndex default constructor savings.
