[fpc-devel] Fixes for i386/x86_64 assembler

[avx512 at t-online.de]

Hi Gareth,
 
i have fixed this bug in the last year (my avx512-branch) and Florian has 
merged my avx512-branch to trunk (23.10.2019).

Hi everyone,
I made some fixes to the compiler when it comes to SSE and AVX instructions 
that deal with single (rather than packed) data, since it got the memory 
sizes wrong and assumed they were 128-bit or 256-bit instead.  Thanks to 
Marco for pointing out that it was single data in issue #32219 - I 
completely overlooked that.
Details and patches are here:

<https://bugs.freepascal.org/view.php?id=35700>
What it means is that the following will now compile without any warnings 
or errors on i386 and x86_64:

ADDSD XMM0, QWORD PTR [EAX] ADDSD XMM0, [EAX] ADDSD XMM0, VarOfTypeDouble

And with other instructions of a similar format.
Gareth aka. Kit
