Some diagnostics are issues late, e.g. in avr_print_operand().
This patch uses the insn's location as a proxy for the operand
location. Without the patch, the location is usually input_location,
which points to the closing } of the function body.

Logic 8-bit shifts with an offset of 6 can be improved by
supporting them as 3-operand operations.

As a matter of interest, is the timeout/memory exhaustion observed with
When splitting multi-byte REG-REG moves in try_split_any(),
it's not clear whether propagating constants will turn
out as profitable. When MOVW is available, split into
REG-REG moves instead of a possible REG-CONST.

This patch splits 2-byte and 3-byte shifts after reload into
a 3-operand byte shift and a residual 2-operand shift.
The "2op" shift insn alternatives are not needed and removed because
all shift insn already have a "r,0,n" alternative that does the job.
