[PATCH] D68857: [X86] Add strict fp support for operations of X87 instructions

Rebase.
STRICT_FP_ROUND has been set as custom so I remove setting it as legal. When entering the custom processing function, if the operand type is legal,the function behaves the same as setOperationAction(ISD:STRICT_FP_ROUND, TYPE, legal)
Modify the test case. Since we do not disable sse, we can pass float-pointer value by register instead of passing by pointer.
