Luiz Capitulino c8c14bcb72 target-i386: x86_cpu_get_phys_page_debug(): support 1GB page translation
Linux guests, when using more than 4GB of RAM, may end up using 1GB pages
to store (kernel) data. When this happens, we're unable to debug a running
Linux kernel with GDB:

(gdb) p node_data[0]->node_id
Cannot access memory at address 0xffff88013fffd3a0
(gdb)

GDB returns this error because x86_cpu_get_phys_page_debug() doesn't support
translating 1GB pages in IA-32e paging mode and returns an error to GDB.

This commit adds support for 1GB page translation for IA32e paging.
