LOG: [lldb/crashlog] Add support for 32bit frame addresses
This patch adds support for 32bit stack frame addresses in the `crashlog`
command.
For crash reports that are generated from a arm64_32 process, `PAGEZERO`
is loaded at 0x00004000 so no code address will be less than 0x4000.
This patch changes the crashlog frame address regex group to match
addresses as small as 4 hex characters.
