[IR] Add getDataLayout() helpers to Function and GlobalValue (#96919) 
Similar to https://github.com/llvm/llvm-project/pull/96902, this adds
`getDataLayout()` helpers to Function and GlobalValue, replacing the
current `getParent()->getDataLayout()` pattern.

d75f9dd1d2 Revert "[IR][NFC] Update IRBuilder to use InsertPosition (#96497)" 
Reverts the above commit, as it updates a common header function and
did not update all callsites:

  https://lab.llvm.org/buildbot/#/builders/29/builds/382

This reverts commit 6481dc57612671ebe77fe9c34214fba94e1b3b27.

[IR][NFC] Update IRBuilder to use InsertPosition (#96497) 
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.

e54277fa10 [NFC][RemoveDIs] Use iterators over inst-pointers when using IRBuilder 
This patch adds a two-argument SetInsertPoint method to IRBuilder that
takes a block/iterator instead of an instruction, and updates many call
sites to use it. The motivating reason for doing this is given here [0],
we'd like to pass around more information about the position of debug-info
in the iterator object. That necessitates passing iterators around most of
the time.

2a26d47a2d [LoopBoundSplit] Check the start value of split cond AddRec 
After transformation, we assume the split condition of the pre-loop is always
true. In order to guarantee it, we need to check the start value of the split
cond AddRec satisfies the split condition.

a2a0ac42ab [SimpleLoopBoundSplit] Split Bound of Loop which has conditional branch with IV 
This pass transforms loops that contain a conditional branch with induction
variable. For example, it transforms left code to right code:

                             newbound = min(n, c)
 while (iv < n) {            while(iv < newbound) {
   A                           A
   if (iv < c)                 B
     B                         C
   C                         }
 }                           if (iv != n) {
                               while (iv < n) {
                                 A
                                 C
                               }
                             }
