* config/tc-mips.c (macro): Handle new macros: "lca" and "dlca"

for loading addresses using CALL relocations.
Don't emit CALL relocations when a base register is used.

* gas/mips/lca-svr4pic.d: New test for the "lca" macro.
* gas/mips/lca-xgot.d: Likewise.
* gas/mips/lca.s: Source for the new tests.
* gas/mips/mips.exp: Run the new tests.

* opcode/mips.h: Define new enum members, M_LCA_AB and M_DLCA_AB.

* mips-opc.c (mips_builtin_opcodes): Handle new macros: "lca" and
"dlca".
