RISC-V: Linux signal frame support.
Make riscv_isa_flen available to the linux native code, and clean up duplicate
comments.
gdb/
* riscv-tdep.c (riscv_isa_xlen): Refer to riscv-tdep.h comment.
(riscv_isa_flen): Likewise. Drop static.
* riscv-tdep.h (riscv_isa_xlen): Move riscv-tdep.c comment to here.
(riscv_isa_flen): Likewise.
