[llvm] llc: Construct RuntimeLibraryInfoWrapper with correct triple (PR #176798)

[Matt Arsenault via llvm-commits]

https://github.com/arsenm created https://github.com/llvm/llvm-project/pull/176798

The target option processing here is unnecessarily confusing
and buggy. Depending on the combination of -march, -mtriple, and
an explicit module in the triple, the triple won't be set in the
IR module. "TheTriple" should be the one consistent with the
constructed TargetMachine.

This avoids a behavior change when SelectionDAG is switched to
using LibcallLoweringInfo.
