This patch changes the format used to print fixed-point constants from
hex to decimal. For instance a negative "short fract" fixed-point
constant may be represented as a signed HOST_WIDE_INT from -1 to -128,
which would currently be printed as e.g. 0xfff....ffxx, resulting in a
"bignum truncated to fit" warning from the assembler. This trouble is
avoided if we just print using integers instead, similarly to the way
signed character-constants are emitted elsewhere in the compiler.
Tested along with the rest of the patch series. OK to apply?

ChangeLog
* final.c (output_addr_const): Print fixed-point constants as
decimal not hex (avoiding an assembler overflow warning for
negative byte constants).
