This patch ensures consistency in the construction of FP_ROUND nodes
such that they always use ISD::Constant instead of ISD::TargetConstant.

This additionally fixes a bug in the AArch64 SVE backend where patterns
were matching against TargetConstant nodes and sometimes failing when
passed a Constant node.
