1fec092f - [AArch64][GlobalISel] Allow selecting FPR index loads. (#143835)

[AArch64][GlobalISel] Allow selecting FPR index loads. (#143835) We can, through legalization of certain operations, end up generating G_INDEXED_LOAD into FPR registers that require entensions. SExt and ZExt will always opt for GPR, but anyext/noext can curently be set to FPR registers in regbankselect. As writing a subregister will set higher bits in the same register to 0, we can successfully handle zext and anyext on FPR registers, which is what this patch attempts to add.
