config/i386/i386.md (UNSPEC_TRUNC_NOOP): New unspec definition.
(X87MODEF): New mode macro.
(ssemodefsuffix): New mode attribute.
(truncxf<mode>2_i387_noop_unspec): New insn pattern.
(sqrt_extend<mode>xf2_i387): New insn pattern.
(sqrt<mode>2): For non-SSE sqrt, emit sqrt_extend<mode>xf2_i387
insn and truncate result back to original mode using
UNSPEC_TRUNC_NOOP truncation.
(*sqrt<mode>2_sse): Implement using SSEMODEF mode macro and
ssemodefsuffix mode attribute.
(*sqrtsf2_mixed, *sqrtsf2_i387, *sqrtdf2_mixed, *sqrtdf2_i387)
(*sqrtextendsfdf2_i387, *sqrtextendsfxf2_i387)
(*sqrtextenddfxf2_i387): Remove insn patterns.
(fmodsf3, fmoddf3, remaindersf3, remainderdf3): Use noop
truncation patterns.
reg-stack.c (get_true_reg): Handle UNSPEC_TRUNC_NOOP.
