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.

Check for stack space more intelligently. libgcc sets the stack limit field in TCB to 256 bytes above the actual allocated stack limit. This means if the function's stack frame needs less than 256 bytes, we can just compare the stack pointer with the stack limit. This should result in lesser calls to __morestack. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@145766 91177308-0d34-0410-b5e6-96231b3b80d8

Check for stack space more intelligently. libgcc sets the stack limit field in TCB to 256 bytes above the actual allocated stack limit. This means if the function's stack frame needs less than 256 bytes, we can just compare the stack pointer with the stack limit. This should result in lesser calls to __morestack. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@145766 91177308-0d34-0410-b5e6-96231b3b80d8
