Dave Estes f657899174 [AArch64] Refines the Cortex-A57 Machine Model
Primarily refines all of the instructions with accurate latency
and micro-op information. Refinements largely focus on the NEON
instructions.

Additionally, a few advanced features are modeled, including
forwarding for MAC instructions and hazards for floating point SQRT
and DIV.

Lastly, the issue-width is reduced to three so that the scheduler
will better accommodate the narrower decode and dispatch width.

// Contains all of the Cortex-A57 specific SchedWriteRes types. The approach
// below is to define a generic SchedWriteRes for every combination of
// latency and microOps. The naming conventions is to use a prefix, one field
// for latency, and one or more microOp count/type designators.
// Prefix: A57Write
// Latency: #cyc
// MicroOp Count/Types: #(B|I|M|L|S|X|W|V)
//
// e.g. A57Write_6cyc_1I_6S_4V means the total latency is 6 and there are
// 11 micro-ops to be issued down one I pipe, six S pipes and four V pipes.
