Fix PR ada/38127

[Eric Botcazou]

This is yet another fallout of the recent switch to using a true boolean type.
It turns out that special-casing boolean types in make_type_from_size was not 
a very good idea as the middle-end really expects types of integral bitfields 
to have a precision greater or equal to the size of the bitfield.

Tested on i586-suse-linux, applied on the mainline.
