[PATCH 10/52] jit: Replace uses of {FLOAT,{,LONG_}DOUBLE}_TYPE_SIZE

[Kewen Lin]

Joseph pointed out "floating types should have their mode,
not a poorly defined precision value" in the discussion[1],
as he and Richi suggested, the existing macros
{FLOAT,{,LONG_}DOUBLE}_TYPE_SIZE will be replaced with a
hook mode_for_floating_type.  Unlike the other FEs, for the
uses in recording::memento_of_get_type::get_size, since
{float,{,long_}double}_type_node haven't been initialized
yet, this is to replace {FLOAT,{,LONG_}DOUBLE}_TYPE_SIZE
with calling hook targetm.c.mode_for_floating_type.

gcc/jit/ChangeLog:

        * jit-recording.cc (recording::memento_of_get_type::get_size): Update
        macros {FLOAT,DOUBLE,LONG_DOUBLE}_TYPE_SIZE by calling
        targetm.c.mode_for_floating_type with
        TI_{FLOAT,DOUBLE,LONG_DOUBLE}_TYPE.
