Gold plugins may wish to further process an input file added by a plugin. For
example, the plugin may need to assign a unique segment for sections in a
plugin-generated input file. This patch adds a plugin callback that the linker
will call when reading symbols from a new input file added after the
all_symbols_read event (i.e. an input file added by a plugin).

For the most part, testcases under gcc.target/arm/cmse/baseline and
gcc.target/arm/cmse/mainline are duplicate copies with only different
dejagnu directives. Although there is no requirement for them to be
similar, having them both identical allow to compare the code generated
and make it easier in case of change in code generation to both
architecture to update the testcases (if one needs updating so does the
other).

Similarly all the tests in gcc.target/arm/cmse/mainline/<floatabi> have
the same source but are duplicate copies.

This patch moves all the code in the tests to a parent directory:
gcc.target/arm/cmse for tests shared by Armv8-M Baseline and Mainline
and gcc.target/arm/cmse/mainline for tests *only* shared by the various
float ABI of Armv8-M Mainline. C includes are then used where the code
used to sit.

Note that the cmse-13.c test used to differ slightly between
architectures and float ABI tested in the first floating-point constant
passed to bar: sometimes 1.0 and sometimes 3.0. This patch settles on
3.0 to not confuse with the 1.0 constant used to clear VFP registers in
some of the configurations.
