Intel LLVM + MAPL2 Issues

[mathomp4]

As a much delayed follow on to #1890, we now look at getting MAPL to work with ifx the Intel LLVM compiler.

To test this, on discover you replace g5_modules with:

/gpfsm/dhome/mathomp4/GitG5Modules/SLES15/7.19.0/g5_modules.ifx2024_0_0.impi2021_11

and the build is successful. 🎉

But the tests are not:

6% tests passed, 63 tests failed out of 67

The failing tests are:

The following tests FAILED:
	  2 - MAPL.pfio.tests (Failed)
	  3 - pFIO_tests_mpi (Failed)
	  4 - pFIO_tests_simple (Failed)
	  5 - pFIO_tests_hybrid (Failed)
	  6 - pFIO_tests_mpi_2comm (Failed)
	  7 - pFIO_tests_mpi_2group (Failed)
	  8 - pFIO_performance (Failed)
	  9 - MAPL.profiler.tests (Failed)
	 13 - MAPL.base.tests (Failed)
	 14 - bundleio_tests_latlon (Failed)
	 15 - bundleio_tests_cube (Failed)

plus all the ExtData tests it looks like.

I guess one hope might be that once something is figured out, it can be applied en masse?
