<details>
<summary>Changes</summary>
This patch is intended to be the first of a series with end goal to adapt atomic optimizer pass to support i64 and f64 operations (along with removing all unnecessary bitcasts). This patch introduces pseudos for 64bit readlane, writelane and readfirstlane ops which are lowered post ISel. Requesting comments on the approach here,
still TODO in this patch :
1. add f32 pattern to select read/writelane operations (should this be a seperate patch ?)
2. add/update tests for readfirstlane and writelane ops.
