70a3b77df8 Add 'lit' support for llvm tests.
- This adds 'make check-lit' from the top-level Makefile.

ba3598cb1f fix PR4767, a crash because fp stackifier visited blocks in
depth first order, so it wouldn't process unreachable blocks.
When compiling at -O0, late dead block elimination isn't done
and the bad instructions got to isel.

4cb81bdd56 instcombine transforms vector loads that are only used by
extractelement operations into a bitcast of the pointer,
then a gep, then a scalar load.  Disable this when the vector
only has one element, because it leads to infinite loops in
instcombine (PR4908).

This transformation seems like a really bad idea to me, as it
will likely disable CSE of vector load/stores etc and can be
better done in the code generator when profitable.  This
goes all the way back to the first days of packed types,
r25299 specifically.

I'll let those people who care about the performance of vector
code decide what to do with this.

fd06aa7c07 Fix a thinko: When lowering fneg with xor, bitcast the operands
from floating-point to integer first, and bitcast the result
back to floating-point. Previously, this test was passing by
falling back to SelectionDAG lowering. The resulting code isn't
as nice, but it's correct and CodeGen now stays on the fast path.

da4ae4be5b Stabilize the order of live intervals in the priority_queue used by the
linear scan reg alloc.  This fixes a problem I ran into where extracting
a function from a larger file caused the generated code to change (masking
the problem I was trying to debug) because the allocator behaved differently.

This changes the results for two X86 regression checks.  stack-color-with-reg
is improved, with one less instruction, but pr3495 is worse, with one more
copy.  As far as I can tell, these tests were just getting lucky or unlucky,
so I've changed the expected results.

859fff476d Include optional subclass flags, such as inbounds, nsw, etc., in the
Constant uniquing tables. This allows distinct ConstantExpr objects
with the same operation and different flags.

Even though a ConstantExpr "a + b" is either always overflowing or
never overflowing (due to being a ConstantExpr), it's still necessary
to be able to represent it both with and without overflow flags at
the same time within the IR, because the safety of the flag may
depend on the context of the use. If the constant really does overflow,
it wouldn't ever be safe to use with the flag set, however the use
may be in code that is never actually executed.

This also makes it possible to merge all the flags tests into a single test.

b405bbe664 Replace ocamlc tests with ocamlopt tests since they're less noisy.
There's a bug with ocamlc that uses "char*" instead of "const char*" for
global string variables. This causes g++ to be very noisy when linking
ocamlc programs. That's why the ocaml test used to cat to /dev/null.
ocamlopt doesn't have this problem, so we can get rid of the >/dev/null,
which may obscure some problems.
