tcg: Add extended GETPC mechanism for MMU helpers with ldst optimization
Add GETPC_EXT which is used by MMU helpers to selectively calculate the code address of accessing guest memory when called from a qemu_ld/st optimized code or a C function. Currently, it supports only i386 and x86-64 hosts. Signed-off-by: Yeongkyoon Lee <yeongkyoon.lee@samsung.com> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
