[svn-r24171] Purpose: Fix problem with gcc 4.8
Description: With optimization enabled, gcc 4.8 inserts garbage into the padding bytes of floating point types when assigning from a literal constant. This caused problems when H5detect.c scanned the bits in floating point types to determine their properties. Modified H5detect.c to scan for padding before further analyzing the type, and to ignore all information in the padding areas. Also removed code that temporarily disabled optimization. Tested: jam, koala, ostrich, platypus (h5committest)
