Relax requirements on asm for non-BIOS i386 platforms. These platforms don't have a hard limit on size of resulting code16 code, so we don't care if assembly is bigger than necessarry.

/* on x86 old clang doesn't support .code16
newer clang supports it but creates 6-byte jumps instead of 3-byte ones
which makes us go over boot sector size. */

asm-tests/i386-pc: Check that near jumps are 2 bytes. We already check that jump over 300 bytes gap is 3 bytes in code16-mode. Some clang versions generate 3-byte opcode for short jumps which makes boot.img blow over 512-byte limit. Enforce -no-integrated-as in such cases
