Revert "Revert r305164/5/7." Restore the `-gz` option to the driver with some minor tweaks to handle the additional case for `-Wa,--compress-debug-sections`. This intends to make the compression of the debug information controllable from the driver. The following is the behaviour: -gz enable compression (ambiguous for format, will default to zlib-gnu) -gz=none disable compression -gz=zlib-gnu enable compression (deprecated GNU style zlib compression) -gz=zlib enable compression (zlib based compression) Although -Wa,-compress-debug-sections works, it should be discouraged when using the driver to invoke the assembler. However, we permit the assembler to accept the GNU as style argument --compress-debug-sections to maintain compatibility. Note, -gz/-gz= does *NOT* imply -g. That is, you need to additionally specific -g for debug information to be generated. llvm-svn: 306115
