This patch extends the LoopUnroll pass to be able to unroll loops
...
with unknown trip counts. This is left off by default, and a
command-line option enables it. It also begins to separate loop
unrolling into a utility routine; eventually it might be made usable
from other passes.
It currently works by inserting conditional branches between each
unrolled iteration, unless it proves that the trip count is a
multiple of a constant integer > 1, which it currently only does in
the rare case that the trip count expression is a Mul operator with
a ConstantInt operand. Eventually this information might be provided
by other sources, for example by a pass that peels/splits the loop
for this purpose.

If an alloca only has two types of uses: 1) reads 2) a memcpy/memmove that
...
copies from a constant global, then we can change the reads to read from the
global instead of from the alloca. This eliminates the alloca and the memcpy,
and promotes secondary optimizations (because the loads are now loads from
a constant global).
This is important for a common C idiom:
void foo() {
int A[] = {1,2,3,4,5,6,7,8,9...};
... only reads of A ...
}
For some reason, people forget to mark the array static or const.
This triggers on these multisource benchmarks:
