[AArch64] Removed redundant FMOV instruction for truncstores of f64/f32 via bitcast to i64/i32/i8. (#149997)
Previously, storing the low bits of a double, which was bitcast to i64
and truncated to i32 or i16, would emit a redundant FMOV. This patch
introduces new TableGen patterns to avoid the unnecessary FMOV. Tests
added: bitcast_truncstore.ll
