[PATCH 0/2] Fix for printf_size and IEEE binary128 implementation

["Gabriel F. T. Gomes" <gabriel at inconstante dot eti dot br>]

The first patch in this set changes how __printf_fp treats the
floating-point argument.  This change is reflected in printf_size
behaviour, but I'm not sure if this requires a bugzilla entry.

The second patch uses the new behaviour to implement the IEEE binary128
version of printf_size.  Testing has been done on my personal branch [1]
(which has the code to actually enable the building of ieee128-* files
and tests).

Are these two patches OK for master?
