140220bd23 Disable branch protection for arm64. 
This causes failures in signal handler tests, because it looks like clang
doesn't understand how to enable the stack protection in a signal handler.
Clang winds up scribbling on the real stack.

Bug: 149934069
Bug: 151372823

Test: Ran all unit tests on bonito/taimen and the signal handler tests pass.

fdd5eb1977 Add explicit state for heapprofd hooking. 
The double hooking is currently controlled by two separate atomic
booleans. In this state, it is very hard to guard against very subtle
race conditions. Adding an explicit enum to encode the state makes it
easier to reason about the behaviour of the program.

Also introduce a MaybeModifyGlobals to consistently guard accesses to
globals. We would sometimes modify them without swapping the
gGlobalsMutating, introducing a window for race with
HandleHeapprofdSignal.

Test: while true; do atest HeapprofdCtsTest; done
Test: flash blueline and manually test profile

8dba7fefb0 Statically link libdl.a to linker 
When libbase is built for an APEX, it uses dlsym to reflectively access
liblog symbols that are added in R. This is because the APEX where
libbasse is packaged into might be running in pre-R devices where the
symbols don't exist in liblog.so.

This however causes a problem for a static executable in an APEX. Since
it is in an APEX, the dlsym is used. But libdl.so which provides dlsym
is not available to static executable. Currently, the dynamic linker is
the only executable in an APEX that all of its dependencies are
statically linked. Fixing the issue by providing fake dlsym by
statically linking to libdl.a.

afa983c8d4 Rewrite __cxa_atexit / __cxa_finalize 
Simplify:
 - Use a single memory-mapped region to hold the table of destructors.
   Double its capacity each time it is expanded.
 - Add a recompaction pass at the end of __cxa_finalize that shifts
   entries forward and uses madvise to clean pages.
