gcc-force-options: Create symlink gcc-real to allow acceleration of gcc with forced options.
gcc-force-options script moves gcc binary from /usr/bin/gcc to /usr/bin/gcc-real.
To correctly accelerate new binary qemu-binfmt requires symlink in /emul dirrectory.

Backport manual fixes for GCC in order to fix various build and runtime errors.
- Return to old hash table.
- Define missing void_zero_node macro.
- Add missing tree_int_cst_le function.
- Add missing gcc/signop.h header.
- Add missing macro.
- Add missing specialization stuff for double_int class.
- Add missing wi::clz and wi::clrsb functions. Add new file wide-int.cc.
- Remove include of double-int.h from gcc/gengtype.c and gcc/gengtype-state.c.
- Small fix for hash table. Change operator '->' to '.' because we have
a reference to hash table, not a pointer.
- Change varpool_node::finalize_decl (var) back to varpool_finalize_decl (var).
- Fix sanopt.c optimizing part to fit old style pointer map.
- Fix for CHECK_TYPE_SIZE(__kernel_old_uid_t) and CHECK_TYPE_SIZE(__kernel_old_gid_t)
fails on Aarch64.
- Replace gcall back to gimple_statement_call.
- Use old cgraph interface.
- Define missing void_node macro.
- Add missing SUBREG_PROMOTED_SIGN macro.
- Fix ICE in ubsan_type_descriptor due to overflow in tree_fits_uhwi_p.
