<!--LLVM PR SUMMARY COMMENT-->
@llvm/pr-subscribers-backend-arm
Author: Stephen Tozer (SLTozer)
<details>
<summary>Changes</summary>
Uses the new InsertPosition class (added in #<!-- -->94226) to simplify some of the IRBuilder interface, and removes the need to pass a BasicBlock alongside a BasicBlock::iterator, using the fact that we can now get the parent basic block from the iterator even if it points to the sentinel. This patch removes the BasicBlock argument from each constructor or call to setInsertPoint.
This has no functional effect, but later on as we look to remove the `Instruction *InsertBefore` argument from instruction-creation (discussed [here](https://discourse.llvm.org/t/psa-instruction-constructors-changing-to-iterator-only-insertion/77845)), this will simplify the process by allowing us to deprecate the InsertPosition constructor directly and catch all the cases where we use instructions rather than iterators.
