[llvm] [llvm/IR] Fix module build issue following e57308b063bb (NFC) (PR #94580)

[Med Ismail Bennani via llvm-commits]

https://github.com/medismailben created https://github.com/llvm/llvm-project/pull/94580

This patch fixes a build issue following e57308b063bb when enabling module build (`-DLLVM_ENABLE_MODULES=On`).

With that change, we failed to build the LLVM_IR module since `GEPNoWrapFlags` wasn't defined prior to using it.

This patch addresses that issue by including the right header in `llvm/IR/Constant.h` which is also included by most headers in the LLVM_IR module. This should ensure that we can always build it.

This patch fixes a build issue following e57308b063bb when enabling
module build.

With that change, we failed to build the LLVM_IR module since
GEPNoWrapFlags wasn't defined prior to using it.

This patch addressed that issue by including the right header in
`llvm/IR/Constant.h` which is also included by most headers in the
LLVM_IR module. This should ensure that we can always build it.
