The INT3 call emulation selftest is a bit fragile as it relies on the compiler not inserting any extra instructions before the int3_selftest_ip() definition. Also, the int3_selftest_ip() symbol overlaps with the int3_selftest symbol(), which can confuse objtool. Fix those issues by slightly reworking the functionality and moving int3_selftest_ip() to a separate asm function. While at it, improve the naming.
