[x86 PATCH] Split SUBREGs of SSE vector registers into vec_select insns.

This patch is the final piece in the series to improve the ABI issues affecting PR 88873. The previous patches tackled inserting DFmode values into V2DFmode registers, by introducing insvti_{low,high}part patterns. This patch improves the extraction of DFmode values from v2DFmode registers via T
