cplus_demangle_fill_component: Handle DEMANGLE_COMPONENT_RVALUE_REFERENCE

... missed doing the same change to cplus_demangle_fill_component that
was done to d_make_comp. I.e., teach it to only validate that we're
not passing in a "right" subtree. GDB has recently (finally) learned
about rvalue references, and a change to make it use
cplus_demangle_fill_component more ran into an assertion because of
this.

[ARC] Fix move_double_src_operand predicate.
Durring compilation process, (subreg (mem ...) ...) can occur. Hence,
we need to check if the address of mem is a valid one. This patch is
fixing this check by directly calling the address_operand, instead of
calling move_double_src_operand, as the latter is always checking
against the original mode, thus, returning false when the inner and
outer modes are different.

[ARC] Fix detection of long immediate for load/store operands.
ARC can use scaled offsets when loading (i.e. ld.as rA,[base,
offset]). Where base and offset can be a register or an immediate
operand. The scaling only applies on the offset part of the
instruction. The compiler can accept an address like this:
(plus:SI (mult:SI (reg:SI 2 r2 [orig:596 _2129 ] [596])
(const_int 4 [0x4]))
(const_int 60 [0x3c]))
Hence, to emit this instruction we place the (const_int 60) into base
and the register into offset to take advantage of the scaled offset
facility of the load instruction. As a result the length of the load
instruction is 8 bytes. However, the long_immediate_loadstore_operand
predicate used for calculating the length attribute doesn't recognize
this address and returns a wrong decision leading to a wrong length
computation for a load instruction using the above address.
