0f5aed5648 Make the llvm-runtest function much more amenable by eliminating all the
global variables that needed to be passed in. This makes it possible to
add new global variables with only a couple changes (Makefile and llvm-dg.exp)
instead of touching every single dg.exp file.

6b8a6b50d9 Add a test case for testing basic IR features via llvm2cpp. This helps find
bit rot in llvm2cpp and also tests the LLVM C++ IR in ways that llvm-as
doesn't.

0aac889d71 Update the way llvm2cpp tests are done:
1. Make sure bytecode/assembly inputs are always redirected stdin so that
   the module name is <stdin>. This helps not get false negatives when the
   diff is done.
2. Scan the test file to determine if llvm-upgrade needs to be run.
3. Avoid running testings that are XFAIL'd because they'll cause a failure
   when run for llvm2cpp.
4. Get some better error message output.

20a35c3fa5 Teach the codegen to turn [aez]ext (setcc) -> selectcc of 1/0, which often
allows other simplifications.  For example, this compiles:
int isnegative(unsigned int X) {
   return !(X < 2147483648U);
}

Into this code:

x86:
        movl 4(%esp), %eax
        shrl $31, %eax
        ret
arm:
        mov r0, r0, lsr #31
        bx lr
thumb:
        lsr r0, r0, #31
        bx lr

instead of:

x86:
        cmpl $0, 4(%esp)
        sets %al
        movzbl %al, %eax
        ret

arm:
        mov r3, #0
        cmp r0, #0
        movlt r3, #1
        mov r0, r3
        bx lr

thumb:
        mov r2, #1
        mov r1, #0
        cmp r0, #0
        blt LBB1_2      @entry
LBB1_1: @entry
        cpy r2, r1
LBB1_2: @entry
        cpy r0, r2
