The C2y function uimaxabs has been renamed to umaxabs. Implement this change in glibc, keeping a compat symbol under the old name, copying the test to test the new name and changing the old test to test the compat symbol. Jakub has done the corresponding change to the built-in function in GCC. Tested for x86_64 and x86.
