Subject: [lra] patch to fix GCC testsuite degradations on x86

The following patch fixes all current GCC testsuite degradations of IRA+LRA in comparison with IRA + reload on x86 bringing IRA+LRA having less testsuite failures on x86 than IRA+reload.

The patch was successfully bootstrapped on x86-64, IA64, and ppc64.

* lra-int.h (lra_invalidate_insn_data): New prototype.

        * lra.c (lra_invalidate_insn_data): Split out from ...
        (lra_set_insn_deleted): ... here.

        * lra-constraints.c (curr_insn_transform): Call
        lra_invalidate_insn_data and return true for wrong asm insn.
        (lra_constraints): Use dest_reg instead of SET_DEST (set).
