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.

ad9040443c new compile errors for setGlobalAlign and setGlobalSection builtins

fb492d19eb zig build system supports building a library 
See #329

Supporting work:
 * move std.cstr.Buffer0 to std.buffer.Buffer
 * add build.zig to example/shared_library/ and add an automated test
   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

7f47b0c271 run alwaysinline pass in debug mode 
before this commit, the optimized IR code that is displayed in
--verbose mode is not actually what gets emitted to an object
file.

that is now corrected, and we make sure to run the alwaysinliner
pass even in debug mode, so you can rely on "inline" keyword
inlining a function, guaranteed.
