    AArch64/opcodes: Correct another `index' global shadowing error
    
    Fix a commit c2c4ff8d52a2 ("[AArch64] Add ARMv8.3 FCMLA and FCADD
    instructions") build regression:
    
    cc1: warnings being treated as errors
    .../opcodes/aarch64-dis.c: In function 'aarch64_ext_sve_addr_rr_lsl':
    .../opcodes/aarch64-dis.c:1324: error: declaration of 'index' shadows a global declaration
    /usr/include/string.h:303: error: shadowed declaration is here
    make[4]: *** [aarch64-asm.lo] Error 1
    
    in a way following commit 91d6fa6a035c ("Add -Wshadow to the gcc command
    line options used when compiling the binutils.").
    
    	opcodes/
    	* aarch64-asm.c (aarch64_ins_reglane): Rename `index' local
    	variable to `reglane_index'.
