i386: Disable *<absneg:code><mode>2_i387_1 for TARGET_SSE_MATH modes
This pattern interferes with *<absneg:code><mode>2_1 when TARGET_SSE_MATH
modes are active. Combine pass is able to remove (use) RTXes and transforms
*<absneg:code><mode>2_1 to *<absneg:code><mode>2_i387_1 where SSE
alternatives are not available.
