Cannot handle multiple ASM constraints

Extended Description

This program:

unsigned long int foo(unsigned long int in1, unsigned long int in2)
{
unsigned long int result;

asm("{a%I5|add%I5c} %0,%1,%2"
: "=&r"(result)
: "r"(in1), "rI"(in2));
return result;
}

Gives this ICE:

$ llvm-gcc.install/bin/gcc -c bad.c
bad.c: In function 'foo':
bad.c:5: error: operand number out of range
/Users/wendling/llvm/llvm.src/lib/CodeGen/SelectionDAG/SelectionDAGISel.cpp:2459: failed assertion
`Constraints[i].Codes.size() == 1 && "Only handles one code so far!"'
bad.c: At top level:
bad.c:9: internal compiler error: Abort trap
Please submit a full bug report,
with preprocessed source if appropriate.
See URL:http://llvm.org/bugs for instructions.

This is more fall-out from the GMP compilation.

Yep, known issue. In the meantime you can s/rI/r/ to work around this.
