820b667e1b - rm the OP_IMUL to SHL optimization from tcgx86.a_op_const_reg and tcgx86.a_op_const_ref, because it's already done in optimize_op_const, which is called in the beginning of both methods.

f2096de53a * tcg386.g_proc_exit: instead of recalculating stack size, use current_procinfo.final_localsize which was calculated in g_proc_entry. 
* tcgx86.g_proc_entry: don't over-allocate stack in SEH finalizer procedures.

179586f589 + SEH support for Win32. Enable by cycling with OPT=-dTEST_WIN32_SEH. 
Although basic things work (no regressions in test suite, also with TEST_OPT=-O2), there are some secondary issues/TODOs:
- Exception frame around PASCALMAIN is not properly removed in DLLs
- No stack traces yet
- Stack overallocated in finalizer procedures, their entry/exit code needs cleanup
- Signals unit is probably completely broken.

d0f988f7a8 * don't use LEA in the code generator on i8086, as this breaks it quite badly. 
While it is possible to use 16-bit LEA on the i8086, it's probably not worth
  doing it in the code generator, because of the unpleasant register
  restrictions that 16-bit references have.

5c4abfa75a + Implemented saving/restoring registers using PUSH/POP instructions on i386 targets with non-fixed stack. Provides some advantage in code size (e.g. the compiler becomes about 20KBytes smaller). 
* This should be applicable to i8086 targets as well (but needs testing), by copying changes from i386/cgcpu.pas to i8086/cgcpu.pas and removing "$ifdef i386" lines in cgx86.pas.

5d628b29bb * set the subregsize of OS_M64 SSE registers to R_SUBQ so we can 
differentiate between 64 bit and 128 bit (R_SUBMMWHOLE) SSE vector regs,
    and support spilling/assembling for R_SUBQ SSE registers (8 bytes)
    (mantis #23962)

    We currently never use the full 128 bit of an SSE register, and
    spilling for those hasn't been implemented yet either (R_SUBMMWHOLE
    SSE regs are spilled into a 4-byte temp currently -> can overwrite data)

7530fb3352 * tcgx86.make_simple_ref: handle references to absolute addresses (these are quite rare on x86_64, but still worth to handle correctly). 
* If possible, use reference base instead of index, this yields shorter instructions.
* Added comment about offset limits for rip-relative addressing.
- Removed code related to taking threadvar address on win32, it is incorrect because Windows TLS is not directly accessible via segment registers (fs:0x2c points to array of pointers to TLS storages of each module, so at least double indirection is needed).
