AVR cc0 conversion
See https://gcc.gnu.org/pipermail/gcc-patches/2021-January/563638.html
for background.
This patch converts the avr backend to MODE_CC. It addresses some of
the comments made in the previous submission over here
(https://gcc.gnu.org/pipermail/gcc-patches/2020-December/561757.html).
Specifically, this patch has
1. Automatic clobber of REG_CC in inline asm statements, via
TARGET_MD_ASM_ADJUST hook.
2. Direct clobber of REG_CC in insns emitted after reload (pro and
epilogue).
3. Regression testing done on atmega8, atmega128, attiny40 and
atxmega128a3 devices (more details below).
4. Verification and fixes for casesi and avr_compare_pattern related
code that inspects insns, by looking at avr-casesi and mach RTL dumps.
5. Use length of parallel instead of passing in operand counts when
generating code for shift patterns.
6. Fixes for indentation glitches.
7. Removal of CC_xxx stuff in avr-protos.h. In the places where the
macros were still used (cond_string), I've replaced them with a bool
hardcoded to false. I expect this will go away/get fixed when I
eventually add specific CC modes.
Things still to do:
1. Adjustment of peepholes/define_splits to match against patterns
with REG_CC clobber.
2. Model effect of non-compare insns on REG_CC using additional CC
modes. I'm hoping to use of a modified version of the cc attribute
and define_subst (again inspired by the cris port), to do this.
3. RTX cost adjustment.

define_insn_and_split style patterns where the splitter
adds a clobber of the condition code register. Drop "cc"
