Add a bug fix for LLVM as patch, applied by conan build

[mhillenbrand]

For constant ops from arithmetic constants, MLIR chooses SSA value names that reflect the constant. That failed for ints with > 64 bits as the function that derived that name used a shortcut that did not apply (and assert(), as here) for ints with more than 64 bits.

We have contributed a fix to upstream LLVM in llvm/llvm-project@1ef32e7 and need to add this patch into our build of LLVM 14.0.6.

Fixes #46

The build seems to be failing because the patch file isn't quite matching:

Think we're still hitting the same error:
