libbacktrace_offline was inheriting -Wno-unused-parameter from llvm's
makefiles. Fix an unused parameter warning when compiling for an
unsupported architecture, and return false since *value wasn't
written.
Test: lunch aosp_mips-eng && mma -j

1. Read .ARM.exidx and .ARM.extab, provides these data to libunwind
through AccessMem.
2. In FindProcInfo, search .ARM.exidx for the idx entry of function
containing ip.
3. Add structures to store .ARM.exidx info in DebugFrameInfo, and
clean up the structure.
4. Add tests to test each unwind information (.eh_frame, .debug_frame,
.gnu_debugdata, .ARM.exidx) separately.

Test: No regression in 32-bit and 64-bit backtrace_test on host and
angler.

Remove the logging of an error if a thread disappears before the unwind
can begin. This can happen, so allow the caller to determine if this
is really a problem worth logging.

BacktraceOffline is the only code that uses libLLVM. Create
a new shared library, backtrace_offline.so, that references this
so that including libbacktrace.so doesn't wind up pulling in libLLVM.

This reverts commit ab5e583327.
And statically link llvm libraries on host to remove dependency
on 32-bit llvm shared library which is not included in the prebuilt.

Using llvm makes libbacktrace stops building for 32 bit on linux host x86_64.
This reverts commit c9c6b6ee77.
