[PATCH] [clang] Use -android environment for all compiler-rt libs.

[Evgeniy Stepanov]

I suggest moving this logic into getCompilerRT and getting rid of the Env argument.

Beside the two functions this patch is changing, getCompilerRT is used in some MSVC-specific code which can not have llvm::Triple::Android, and it addSanitizerDynamicList.

The latter is interesting, because the current code is wrong, and the proposed change would fix it. Dot-sym files for android static runtime libraries are already generated with "-android" suffix, and the current implementation would fail to find them. There is no way to test it because android target defaults to shared runtime and there is no -static-libasan flag (as a counterpart to -shared-libasan).
