This reverts commit 282d2ab58f56c89510f810a43d4569824a90c538.

Cont. patch after https://github.com/llvm/llvm-project/pull/75580

A significant number of our tests in C accidentally use functions
without prototypes. This patch converts the function signatures to have
a prototype for the situations where the test is not specific to K&R C
declarations. e.g.,

  void func();

becomes

  void func(void);

This is the eleventh batch of tests being updated (there are a
significant number of other tests left to be updated).

Summary:
Following patch D19265 which enable software floating point support in the Sparc backend, this patch enables the option to be enabled in the front-end using the -msoft-float option.

The user should ensure a library (such as the builtins from Compiler-RT) that includes the software floating point routines is provided.

in order to make testing somewhat more feasible. Has the advantage
of making it easier to find target features as well.

using a string map to canonicalize. Fix up a couple of testcases
that needed changing since we are no longer simply appending features
to the list, but all of their mask dependencies as well.

strings and remove the setting of TargetOptions::UseSoftFloat to
match the code change in llvm r237079.

by erasing the soft-float target feature if the rest of the front
end added it because of defaults or the soft float option.

Add some testing for some of the targets that implement this hack.

This makes sure that the front end is specific about what they're expecting
the backend to produce. Update a FIXME with the idea that the target-features
could be more precise using backend knowledge.
