Use strtod instead of strtold in libiberty/d-demangle.c

strtold is currently used to decode templates which have a floating-point
value encoded inside; but this routine is not available on some systems,
such as Solaris 2.9 for instance.

This patch fixes the issue by replace the use of strtold by strtod.
It reduces a bit the precision, but it should still remain acceptable
in most cases.

libiberty/ChangeLog:

        * d-demangle.c: Replace strtold with strtod in global comment.
        (strtold): Remove declaration.
        (strtod): New declaration.
        (dlang_parse_real): Declare value as double instead of long
        double.  Replace call to strtold by call to strtod.
        Update format in call to snprintf.

	PR rtl-optimization/63475
	* alias.c (true_dependence_1): Always use get_addr to extract
	true address operands from x_addr and mem_addr.  Use extracted
	address operands to check for references with alignment ANDs.
	Use extracted address operands with find_base_term and
	base_alias_check. For noncanonicalized operands call canon_rtx with
	extracted address operand.
	(write_dependence_1): Ditto.
	(may_alias_p): Ditto.  Remove unused calls to canon_rtx.
