initial value.

when not optimizing to work around "unable to generate reloads".
* config/avr/avr.h (TARGET_SWITCHES): Add -mno-tablejump option.
(EXTRA_SECTION_FUNCTIONS): Make the .progmem.gcc_sw_table section
executable if not AVR_MEGA. Make sure jump tables are word-aligned.

index in the table, not multiplied by 2.

* config/avr/libgcc.S (__tablejump__): Rename to __tablejump2__.
Change to expect the word address of the table, multiply it by 2
here and not in the caller. Change "adiw" to faster "inc".

constants until mark_constant_pool time if requested.
(mark_constant_pool): Walk the insn chain even if const_str_htab is
not empty.
(mark_constants): If a SYMBOL_REF for deferred string is found,
output it and remove from hash table.
(output_addressed_constants): Set DEFER to 0 in call to
output_constant_def.
