[x86] Fix some asm problems

Browse Source 
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.
