[Patch libgcc] Enable HCmode multiply and divide (mulhc3/divhc3)
This patch arranges for half-precision complex multiply and divide
routines to be built if __LIBGCC_HAS_HF_MODE__. This will be true
if the target supports the _Float16 type.

libgcc complex multiply is meant to eliminate excess
precision from certain internal values by forcing them to memory in
exactly those cases where the type has excess precision. But in
https://gcc.gnu.org/ml/gcc-patches/2014-09/msg01894.html I
accidentally inverted the logic so that values get forced to memory in
exactly the cases where it's not needed. (This is a pessimization in
the no-excess-precision case, in principle could lead to bad results
depending on code generation in the excess-precision case. Note: I do
not have a test demonstrating bad results.)
Bootstrapped with no regressions on x86_64-pc-linux-gnu. Code size
went down on x86_64 as expected; old sizes:

This improves codesize slightly due to fewer base address calculations:

diagnostic-show-locus.c: handle fixits on lines outside the regular ranges
The diagnostic_show_locus implementation determines the set
of line spans that need printing based on the ranges within the
rich_location (in layout::calculate_line_spans).
Currently this doesn't take into account fix-it hints, and hence
we fail to print fix-it hints that are on lines outside of
those ranges.
This patch updates the implementation to take fix-it hints into
account when calculating the pertinent line spans, so that such fix-it
hints do get printed. It also adds some validation, to ensure that
we don't attempt to print fix-its hints affecting a different source
file.
