Bug ID: 36911
Summary: [X86] Add scheduler classes that account for GPR<->XMM
transfers
Product: libraries
Version: trunk
Hardware: PC
OS: Windows NT
Status: NEW
Severity: enhancement
Priority: P
Component: Backend: X86

Blocks: 36908
Transfers between the x86/GPR and SSE/XMM register files can vary a great deal
between targets, we should create suitable classes instead of using
WriteMove/WriteShuffle etc.
This includes the MOVD/MOVQ, PINSR, PEXTR and EXTRACTPS instructions.
