Choose stdlib for test suite based on target platform.

[flackr]

Summary

When compiling programs for the test suite we currently choose which stdlib to use based on the host platform, but should be basing this on the target platform.

[clayborg]

A few changes, See inlined comments.

test/lldbtest.py

1687

use

self.platformIsDarwin()

instead of:

self.getPlatform() in getDarwinOSTriples()

1737

use `self.platformIsDarwin()`

1824

use `self.platformIsDarwin()`

1841

use `self.platformIsDarwin()`

[flackr]

Use platformIsDarwin instead of manually checking if the platform is in darwin triples.

[flackr]

And done in one more location that slipped by before :-).

test/lldbtest.py

Done.

1737

Done.

1824

Looks good.
