xtensa: use pre- and postincrement FP load/store when available
Earlier versions of xtensa FPU used to support preincrement FP load and
store instructions (lsiu/ssiu). Recent FPU supports postincrement FP
load and store instructions only (lsip/ssip). Use configuration macro to
decide which version is available.

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.
