Ed Maste 1419e9adb5 Run profile tests on FreeBSD
FreeBSD does not have libdl, so set it via lit.cfg instead of the test
input, as with asan.  Also remove it from Darwin test runs - it's not
necessary, but harmless there.

Add FreeBSD to the list of hosts to test.

Saleem Abdulrasool b2aa4726d2 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.

Saleem Abdulrasool 864e0740c0 profile: explicitly link against libdl
Add an explicit link against libdl.  libdl may not be indirectly pulled on some
Linux hosts.  Explicitly link against it.  This should hopefully improve the
state of the build bots.

Duncan P. N. Exon Smith 55e4d66f0c 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.
