D128820 stopped creating div/rem constant expressions by default; this patch removes support for them entirely. The getUDiv(), getExactUDiv(), getSDiv(), getExactSDiv(), getURem() and getSRem() on ConstantExpr are removed, and ConstantExpr::get() now only accepts binary operators for which ConstantExpr::isSupportedBinOp() returns true. Uses of these methods may be replaced either by corresponding IRBuilder methods, or ConstantFoldBinaryOpOperands (if a constant result is required). On the C API side, LLVMConstUDiv, LLVMConstExactUDiv, LLVMConstSDiv, LLVMConstExactSDiv, LLVMConstURem and LLVMConstSRem are removed and corresponding LLVMBuild methods should be used. Importantly, this also means that constant expressions can no longer trap! This patch still keeps the canTrap() method to minimize diff -- I plan to drop it in a separate NFC patch.
