Revert "Revert "Revert "Enable lld for windows"""
This reverts commit 6d8c0a50bc3903f90935e5163e1b9bb46a30d5a9.
The switchover to lld appears to be making adb crash on exit for unclear
reasons. Revert it as a quick fix pending further investigation.
Bug: http://b/134613180
Test: adb.exe under windbg
