* config/i386/i386.c (enum x86_64_reg_class): Define
X86_64_COMPLEX_X87_CLASS.
(x86_64_reg_class_names): Add name for X86_64_COMPLEX_X87_CLASS.
(merge_classes): Handle X86_64_COMPLEX_X87_CLASS.
(classify_argument): XCmode is X86_64_COMPLEX_X87_CLASS.
(examine_argument): X86_64_COMPLEX_X87_CLASS requires two
registers when dealing with a return value.
(construct_container): Handle X86_64_COMPLEX_X87_CLASS.
Eliminate impossible case of two X87/X87UP pairs (this now is
being expressed by a single COMPLEX_X87).
(x86_libcall_value): XCmode gets returned in st0/st1.
