This patch set includes two patches that significantly lower the memory usage of covoar. For a full coverage run of the leon3 BSP on my machine, the peak memory usage falls from 9.6 GB down to 1.4 GB. The cleanup of the ELF and DWARF info had previously been moved from the ExecutableInfo class's constructor to its destructor. This was done to ensure that ExecutableInfo::getSourceAndLine() could utilize the DWARF info. A side effect of that change was increased memory usage. These patches ensure that no ELF or DWARF objects are held by the ExecutableInfo class after construction.
