[PATCH 1/2] tcg: Mark more tcg_out*() functions with attribute 'unused'

[Philippe Mathieu-Daudé]

The tcg_out* functions are utility routines that may or
may not be used by a particular backend. Similarly to commit
4196dca63b8, mark them with the 'unused' attribute to suppress
spurious warnings if they aren't used.

This fixes the build with --enable-tcg-interpreter:

  [98/151] Compiling C object libqemu-arm-softmmu.fa.p/tcg_tcg.c.o
  FAILED: libqemu-arm-softmmu.fa.p/tcg_tcg.c.o
  clang [...] -o libqemu-arm-softmmu.fa.p/tcg_tcg.c.o -c ../tcg/tcg.c
  ../tcg/tcg.c:136:20: error: unused function 'tcg_out_dupi_vec' 
[-Werror,-Wunused-function]
