Fix up compression related test cases Fallout from r205261, ensure it doesn't matter how we disable compressed debug info, even if zlib is missing and that we warn when we don't have zlib and don't warn when we do, all while silently suppressing these tests on the systems they weren't intended for... llvm-svn: 205271

// REQUIRES: nozlib
test: fix negative test case Add missing -### to the driver to ensure that we dont try to run the actual command. The host may not support the IAS. Should fix the SCEI buildbots. llvm-svn: 306123

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
