[SelectionDAG][X86] Add SelectionDAG::getSignedConstant and use it in a few places. (#104555)
PR #80309 proposes to have users of APInt's uint64_t
constructor opt-in to implicit truncation. Currently, that patch
requires SelectionDAG::getConstant to opt-in.
This patch adds getSignedConstant so we can start fixing some of the
cases that require implicit truncation.
