Avoid undefined behaviour with signed expressions
PR 17453
bfd/
* libbfd.c (COERCE16, COERCE32, COERCE64): Use unsigned types.
(EIGHT_GAZILLION): Delete.
binutils/
* dwarf.c (read_leb128): Avoid signed overflow.
(read_debug_line_header): Likewise.
gas/
* config/tc-i386.c (fits_in_signed_long): Use unsigned param and
expression to avoid signed overflow.
(fits_in_signed_byte, fits_in_unsigned_byte, fits_in_unsigned_word,
fits_in_signed_word, fits_in_unsigned_long): Similarly.
* expr.c (operand <'-'>): Avoid signed overflow.
* read.c (s_comm_internal): Likewise.
