[PowerPC] Improve codegen for vector loads using scalar_to_vector This patch aims to improve the codegen for vector loads involving the scalar_to_vector (load X) sequence. Initially, ld->mv instructions were used for scalar_to_vector (load X), so this patch allows scalar_to_vector (load X) to utilize: LXSD and LXSDX for i64 and f64 LXSIWAX for i32 (sign extension to i64) LXSIWZX for i32 and f64 Committing on behalf of Amy Kwan.

[PowerPC] Add a peephole post RA to transform the inst that fed by add If the arch is P8, we will select XFLOAD to load the floating point, and then, expand it to vsx and non-vsx X-form instruction post RA. This patch is trying to convert the X-form to D-form if it meets the requirement that one operand of the x-form inst is the special Zero register, and another operand fed by add inst. i.e. y = add imm, reg LFDX. 0, y --> LFD imm(reg) Reviewers: Nemanjai Differential Revision: https://reviews.llvm.org/D49007 llvm-svn: 340149
