New:

error union types as the condition. See #357

29defd705d back to AT&T syntax for assembly 
this reverts 5c04730534ea7933855429c5fc5dc7b22eba7bc2.

sadly the quality of the intel dialect in llvm's assembly
parser has many frustrating bugs, and generally has unfortunate
syntax.

the plan is to use AT&T for now since it at least works,
and eventually zig will have its own assembly parser for
x86 and it will be as close to NASM as possible.

c6605cba83 blocks check that their statements are void 
closes #291

This changes the error message "return value ignored" to "expression value is ignored".
This is because this error also applies to {1;}, which has no function calls.

Also fix ignored expression values in std and test.
This caught a bug in debug.readAllocBytes where an early Eof error would have been missed.
See #219.

   for it
 * add std.list.List.resizeDown
 * improve std.os.makePath
   - no longer recursive
   - takes into account . and ..
 * add std.os.path.isAbsolute
 * add std.os.path.resolve
 * reimplement std.os.path.dirname
   - no longer requires an allocator
   - handles edge cases correctly
