Lucile Rose Nihlen a567040d77 Update LLVM to c744694c6ae1 (#8096) 
Moves Carbon code away from deprecated `llvm::IRBuilder`
and `llvm::PassBuilder` constructors  

Removes llvm patch 0002 as it landed upstream in
[#234482](https://github.com/llvm/llvm-project/pull/234482)

Removes llvm patch 0004 as it landed upstream in
[#234485](https://github.com/llvm/llvm-project/pull/234485)

Removes llvm patch 0005 as it landed upstream in
[#234489](https://github.com/llvm/llvm-project/pull/234489)

Removes llvm patch 0006 as it landed upstream in
[#234486](https://github.com/llvm/llvm-project/pull/234486)

Adds llvm patch 0013, also uploaded as an upstream
PR in [#239321](https://github.com/llvm/llvm-project/pull/239321)

Updates tests in lower and driver to suit changes to LLVM.
