[arm] Early expansion of usubvdi4.
This patch adds early expansion of usubvdi4, allowing us to handle some
constants in place, which previously we were unable to do.
* config/arm/arm.md (usubvdi4): Allow registers or integers for
incoming operands. Early split the calculation into SImode
operations.
(usubvsi3_borrow): New insn pattern.
(usubvsi3_borrow_imm): Likewise.
From-SVN: r277188
