Reduce the size of a release test_shell from 18mb to 12mb.
Reduce the size of a release test_shell from 18mb to 12mb.

- Strip all symbols.  We previously had many exported symbols.

- GC sections.  -fdata/function-sections make sure each piece of code/data has it's own section, since GC works on an entire section.  I will follow up on the V8 build with the same.

- Remove the ident pragmas.  For example, we previously had a string like:
  GCC: (GNU) 4.2.4 (Ubuntu 4.2.4-1ubuntu1)
  Repeated in the .comment section (one for each object?).  This data is just metadata.
