[PATCH 03/10] target-info: Add functions for querying whether the target is i386 or x86_64

[Thomas Huth <thuth@redhat.com>]

From: Thomas Huth <thuth@redhat.com>

As we already have functions for querying whether the target architecture
is one of the various ppc, arm or s390x flavours, add now some functions
for x86, too, which will come in handy to decide during runtime whether
we are running in 32 or 64-bit mode in the x86 targets.
