The "CPU architecture" field is being filled from the wrong part of

Browse source 
the microdump. The microdump OS/arch line looks like:
O A arm 04 armv7l 3.4.0-perf-g4d6e88e #1 SMP PREEMPT Mon Mar 30 19:09:30 2015
and currently the field that says "armv7l" or "aarch64" is being used
to fill in the CPU arch field in crash. The problem is that on a
64-bit device this field *always* says "aarch64" even when running in
a 32-bit process, and so currently the crash reports for aarch64 are
a mix of 32-bit and 64-bit crashes. We should be using the first field
instead, which just says "arm" or "arm64" and reflects the actual
version of webview (32-bit or 64-bit) which is running.
