Shallow water code crashing with Intel compiler

[Tim Greaves]

Having started to run short and medium tests on CX1, a number of tests using the shallow water code are crashing, some reliably, some sporadically. An example of a reliable crash would be shallow_water_mms_wave, detailed on:

 http://buildbot.ese.ic.ac.uk:8080/builders/shallow_water_mms_wave/builds/94/steps/shell_5/logs/stdio

where the relevant output is (I think!):

Tests noticed to be failing are:

python_shape_dshape_test
python_shape_dshape_test_2d
shallow_water_mms_wave
sw_kelvin_wave
sw_kelvin_wave_xz

[Tim Greaves (tim-greaves)]

Jemma and Colin confirm this code is no longer needed and thus the tests can be removed - still being tested on gcc pending removal from the trunk.
