It fixes the expansion of multiword operations in cases where the
suggested target is a hard register and where CANNOT_CHANGE_MODE_CLASS
forbids word-mode subparts.

It fixes the expansion of multiword operations in cases where the
suggested target is a hard register and where CANNOT_CHANGE_MODE_CLASS
forbids word-mode subparts.

PR45074 is a case where expand_absneg_bit needs to decompose a
multi-word negation operation into separate word_mode operations.
The target of the operation is a global FP register variable.
For various reasons, CANNOT_CHANGE_MODE_CLASS forbids changes
from DFmode to SImode for FP registers, so a
