x86/dumpstack: Introduce die_addr() for die() with #GP fault address
Split __die() into __die_header() and __die_body(). This allows inserting
extra information below the header line that initiates the bug report.
Introduce a new function die_addr() that behaves like die(), but is for
faults only and uses __die_header() and __die_body() so that a future
commit can print extra information after the header line.
[ bp: Comment the KASAN-specific usage of gp_addr. ]
