[llvm-symbolizer][test] Extract tests from llvm-symbolizer.test and simplify (#3)

This is the fourth (and final for now) of a series of patches
simplifying llvm-symbolizer tests. See r352752, r352753 and 352754 for
the previous ones. This patch splits out several more distinct test
cases from llvm-symbolizer.test into separate tests, and simplifies them
in various ways including:

1) Building a test case for spaces in path from source, rather than
   using a pre-canned binary. This allows deleting of said binary and the
   source it was built from.
2) Switching to specifying addresses and objects directly on the
   command-line rather than via stdin.

This also adds an explict test for the ability to specify a file and
address as a line in stdin, since the majority of the tests have been
migrated away from this approach, leaving this largely untested.
