x86-64-asm: Clean up 64bit immediate support
...
Fix it to actually be able to parse 64bit immediates (enlarge
operand value type). Then, generally there's no need for accepting
IM64 anywhere, except in the 0xba+r mov opcodes, so OP_IM is
unnecessary, as is OPT_IMNO64. Improve the generated code a bit
by preferring the 0xc7 opcode for im32->reg64, instead of the
im64->reg64 form (which we therefore hardcode).

x86-asm: Remove old ASM_16 code

This code was inactive since a long time (and was deactivated because

[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.

Improve hash performance
...
- better `TOK_HASH_FUNC`
- increases `hash_ident` initial size to 16k (from 8k)
- `cstr_cat` uses single `realloc` + `memcpy`
- `cstr_cat` can append terminating zero
- `tok_str_realloc` initial size to 16 (from 8)
- `parse_define` uses static `tokstr_buf`
- `next` uses static `tokstr_buf`
- fixes two latent bugs (wrong deallocations in libtcc.c:482 and
tccpp.c:2987)

Change the way struct CStrings are handled.
...
A CString used to be copied into a token string, which is an int array.
On a 64-bit architecture the pointers were misaligned, so ASan gave
lots of warnings. On a 64-bit architecture that required memory
accesses to be correctly aligned it would not work at all.
The CString is now included in CValue instead.

on Linux (Make) and Windows (CMake), so I might've messed
something up on other platforms...
