relative to the normal stack alignment of the target (e.g., when using
ebp as framepointer, all addresses are offset 8 to the stack pointer) in
the temp generator. This enables allocating temps/locals with the correct
alignment as long as the required alignment is not bigger than the
guaranteed stack pointer alignment (fixes mantis #15582 on systems where
the stack pointer is at least aligned to 16 bytes; e.g., not yet on
i386-platforms other than darwin)

symbols on darwin/ppc and darwin/i386, and also for common symbols on
darwin/ppc, as they're not required for other kinds of symbols on those
platforms (gcc doesn't use them either with -O1 and higher; it does use
them always for darwin/ppc64 except for local symbols, and hence so do we)

they don't have explicit side-effects, and if -Oodeadvalues (part of -O4)

+ 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

It is the same as the normal MatchInstruction function but supports to
be called with a set of TAsmOps instead of a single op.

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;
