Details:
This improves support for AVR_TINY architecture.
It'a collection of low hanging fruit from from /libc/misc/ and libc/string,
mostly achieved by
* Using new X_sbiw instead of sbiw
* Replace r0 by __tmp_reg__
* common/asmdef.h (X_sbiw): New asm macro.
* common/macros.inc (X_sbiw): New asm macro.
* libc/misc/itoa.S: Don't restrict to !AVR_TINY.
* libc/misc/itoa_ncheck.S: Same.
* libc/misc/utoa.S: Same.
* libc/misc/utoa_ncheck.S: Same. And use X_sbiw instead of sbiw.
* libc/string/strlcat.S: Same.
* libc/string/strncat.S: Same.
* libc/string/strrev.S: Same.
* libc/string/strrchr.S: Same.
* libc/string/memchr.S: Don't restrict to !AVR_TINY.
[AVR_TINY]: Use "ld __tmp_reg__,-R" instead of "sbiw R,1".
* libc/string/strcat.S: Same.
* libc/string/strchr.S: Same.
* libc/string/memrchr.S: Don't restrict to !AVR_TINY.
(r0): Use __tmp_reg__ instead.
(adiw ZL,0): Use X_sbiw ZL,0 for comparison against 0 instead.
* libc/string/strchrnul.S: Don't restrict to !AVR_TINY.
(r0): Use __tmp_reg__ instead.
[AVR_TINY]: Use "ld __tmp_reg__,-R" instead of "sbiw R,1".
* libc/string/strpbrk.S: Same.
* libc/string/strstr.S: Don't restrict to !AVR_TINY.
Use X_sbiw instead of sbiw.
(chr2): Define to __tmp_reg__ instead of to r0.
* libc/string/strtok_r.S: Don't restrict to !AVR_TINY.
Use X_sbiw instead of sbiw.
(dch) [AVR_TINY]: Push / pop r18 around function.
[AVR_TINY]: Use "ld __tmp_reg__,R+" instead of "adiw R,1".
