645d5a9f4f Use the new %link variable to make this test portable.

641527f3e2 Make new variables available: compile_c, compile_cxx, link to handle tests 
that want to use LLVM's notion of compiling and linking programs. This
includes all the -I -L and optimization switches that LLVM would using to
compile or link any of this files.

d029c7e666 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.

f29754c7b9 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.

60012ded54 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.

        sext i1 %0 to i32               ; <i32>:1 [#uses=1]

65786b078c 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
        bx lr

daa012d1fb Simplify SROA conversion to integer in some ways, make it more general in others. 
We now tolerate small amounts of undefined behavior, better emulating what
would happen if the transaction actually occurred in memory.  This fixes
SingleSource/UnitTests/2007-04-10-BitfieldTest.c on PPC, at least until
Devang gets a chance to fix the CFE from doing undefined things with bitfields :)
