080ec9fadd x86-asm: Consolidate insn descriptions 
Use OPC_BWLX and OPC_WLX in i386-asm.h and x86_64-asm.h to
reduce number of differences between both.

b9f01dffc6 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).

55bd08c5ae x86-asm: Remove old ASM_16 code 
This code was inactive since a long time (and was deactivated because
it was wrong to start with) and just clutters the sources.  Remove
it.

f0fa5603cf x86-64: Run asmtest as well 
This fixes and activates the asm test that's part of tcctest.c
also on x86-64, requiring a small fix for the 'm' constraint.

bd93dc6923 x86: Improve cmov handling

deal with this.

5e47b08dc8 [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.

224236f57c 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)

1c2dfa1f4b 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.

47e06c6d4e Reorganize the source tree. 
* Documentation is now in "docs".
 * Source code is now in "src".
 * Misc. fixes here and there so that everything still works.

I think I got everything in this commit, but I only tested this
on Linux (Make) and Windows (CMake), so I might've messed
something up on other platforms...

50b040ef83 win64: add tiny unwind data for setjmp/longjmp 
This enables native unwind semantics with longjmp on
win64 by putting an entry into the .pdata section for
each compiled fuction.

Also, the function now use a fixed stack and store arguments
into X(%rsp) rather than using push.

1308e8ebcf integrate x86_64-asm.c into i386-asm.c 
Also, disable 16bit support for now as it causes bugs
in 32bit mode.  #define I386_ASM_16 if you want it.

e500c9118a i386-asm: fix imul 
With imul the 3rd operand defaults to the 2nd on.  The previous
logic left 'op_type[2]' uninitialized which caused the bug to
show up only sometimes.

0a3bcb57f6 fix 32bit asm 
The new 16bit code was causing wrong 0x66 prefixes
in 32bit code.

The fix possibly breaks the feature on 16bit asm.
