Instruction scheduling itinerary for Intel Atom. Adds an instruction itinerary to all x86 instructions, giving each a default latency of 1, using the InstrItinClass IIC_DEFAULT. Sets specific latencies for Atom for the instructions in files X86InstrCMovSetCC.td, X86InstrArithmetic.td, X86InstrControl.td, and X86InstrShiftRotate.td. The Atom latencies for the remainder of the x86 instructions will be set in subsequent patches. Adds a test to verify that the scheduler is working. Also changes the scheduling preference to "Hybrid" for i386 Atom, while leaving x86_64 as ILP.

Turn on list-ilp scheduling by default on x86 and x86-64, fix up testcases accordingly. Some are currently xfailed and will be filed as bugs to be fixed or understood. Performance results: roughly neutral on SPEC some micro benchmarks in the llvm suite are up between 100 and 150%, only a pair of regressions that are due to be investigated john-the-ripper saw: 10% improvement in traditional DES 8% improvement in BSDI DES 59% improvement in FreeBSD MD5 67% improvement in OpenBSD Blowfish 14% improvement in LM DES Small compile time impact. llvm-svn: 127208 2011-03-08 03:42:25 +01:00			`; CHECK: divss`

Change the x86 32-bit scheduler to register pressure and fix up the corresponding testcases back to the previous versions. Fixes some performance regressions only seen on 32-bit. llvm-svn: 127441 2011-03-11 02:05:58 +01:00			`; CHECK: divps`
