[asan] Restore asan-rt name on linux back to pre-r216380.
...
There is no reason to have different library names for shared and static
cases on linux. It also breaks Android where we install the shared asan-rt
library into the system and should keep the old name.
This change reverts most of r216380 limiting it to win32 targets only.

DFSan's set label function should avoid writing to the shadow memory when the write would not change the value in memory.
...
When writing a label to shadow memory, don't write if the value is already set to the value being written. This dramatically reduces real memory consumption in programs with sparse use of labels.
Test Plan: It would be nice to test that unnecessary writes are skipped, but I do not see how a unit test could do this.
