Avoid setting or recording negative alignments when the target stores multiple octets in a single byte.
gas * read.c (finish_bundle): Avoid recording a negative alignment.
(do_align): Use unsigned values for n, len and max. Only create
a frag if the alignment requirement is greater than the minimum
byte alignment. Avoid recording a negative alignment.
(s_align): Use unsigned values where appropriate.
(bss_alloc): Use an unsigned value for the alignment.
(sizeof_sleb128): Add a comment noting that we encode one octet
per byte, regardless of the value of OCTETS_PER_BYTE_POWER.
(emit_leb129_expr): Abort if the emitted encoding was longer than
expected.
* read.h (output_leb128): Update prototype.
(sizeof_leb128): Update prototype.
(bss_alloc): Update prototype.
* write.c (record_alignment): Use an unsigned value for the
alignment. Do not record alignments less than the minimum
alignment for a byte.
* write.h (record_alignment): Update prototype.
