01b5e2b6f6 * use the parsed node type for checking the validity of default parameter 
values instead of a default based on the resulting constsym (more robust)

f5de7e34d3 * only remove the calculation of unused parameters of inline routines if 
they don't have explicit side-effects, and if -Oodeadvalues (part of -O4)
    is active (because it can result in the removal of range check errors,
    segmentation faults, etc)

4d0e4e1b56 * treat "[var + rip]" in intel assembler mode as addr_pic_no_got on x86-64 
(mantis #22665)
  + support "[var wrt ..gotpcrel]" nasm/yasm syntax in intel assembler mode
    for GOT-relative accesses on x86-64, + give an error when trying to do
    this on win64 (it doesn't have a GOT)
  * moved code that give a warning when using GOT-relative accesses to
    static data on x86-64 from the AT&T reader to rax86 so it's also
    active for the Intel assembler reader
  + added warning when not using GOT-relative accesses (but plain
    RIP-relative instead) to global data on non-Win64 x86-64

global, and no longer make it global for all symbols when smartlinking

f7dbe6d7a6 * use a different register constant for EIP and RIP (fixes external 
assembler writers on x86-64 after r22181, the shift in positions
    caused every occurrence of RIP to become EIP in the assembler code)

b9fa9da629 Small fixes to OpCmp2OpS 
1.) For UMULL and UMLAL support we would have to make sure the following
code checks RdHi and RdLo, which is currently not supported.
The former code would transform the following

  umull r0, r1, r2, r3
  cmp   r0, #0
  bne   .LSomething

into

  umulls r0,r1,r2,r3
  bne    .LSomething

which is wrong. UMULL has a 64bit result in r1+r0 and checks the full 64bit for 0
before setting the Z flag.

2.) Support MLA.

3.) Support MI/PL/NE/EQ for all instructions. As all of them are setting
the N and Z flags in the same way only based on the result of the
operation not on its input values.

N:=Result[31];
Z:=Result = 0;
