[Hexagon] Improve code generation for 32x32-bit multiplication For multiplications of 64-bit values (giving 64-bit result), detect cases where the arguments are sign-extended 32-bit values, on a per- operand basis. This will allow few patterns to match a wider variety of combinations in which extensions can occur. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@304223 91177308-0d34-0410-b5e6-96231b3b80d8
