InstrProf: Support profiling dlopen'd shared libraries Shared objects are hard. After this commit, we do the right thing when profiling two separate shared objects that have been dlopen'd with `RTLD_LOCAL`, when the main executable is *not* being profiled. This mainly simplifies the writer logic. - At initialization, determine the output filename and truncate the file. Depending on whether shared objects can see each other, this may happen multiple times. - At exit, each executable writes its own profile in append mode. <rdar://problem/16918688> llvm-svn: 209053

profile: adjust flags for libdl dlopen expects that the flags contains RTLD_LAZY or RTLD_NOW. RTLD_LAZY will resolve the symbol on first use, and is generally preferred due to efficiency. Add this to fix the test failure on the build bots. llvm-svn: 209098
