Peter Rong 4a026b5092 [AMDGCN] Use ZExt when handling indices in insertment element (#85718) ...

When i1 true is used as an index, SExt extends it to i32 -1. This would
cause BitVector to overflow.
The language manual have specified that the index shall be treated as an
unsigned number, this patch fixes that.

This patch fixes #85717
