I'm impatient, please make llvm-test faster #1531

Extended Description

Ideas:

Instead of using llvm-gcc -S -emit-llvm + llvm-as to get to the .rbc file for each.c file, just use llvm-
gcc -c -emit-llvm.
To get from linked.rbc to linked.bc, we currently invoke llvm-dis, then 'gccas' (a shell script which
invokes llvm-dis then opt). It would be much better to just run opt!

Both of these would significantly reduce the disk I/O, disk space required, and cpu time requirements for
running llvm-test.

I'm going to try to get this done for tonight's run.

This is now implemented, with these patches:

This significantly speeds up llvm-test, especially on the larger test cases.
Even the smaller test suites are sped up by a second or two.
