[x86] Fix some asm problems
A bag of assembler fixes, to be either compatible with GAS (e.g. order of 'test' operands), accept more instructions, count correct foo{bwlq} variants on x86_64, fix modrm/sib bytes on x86_64 to not use %rip relative addressing mode, to not use invalid insns in tests/asmtest.S for x86_64. Result is that now output of GAS and of tcc on tests/asmtest.S is mostly the same.
