f8084fb1e1 The CIE says that the LSDA point in the FDE section is an "sdata4". That's fine, 
but we need it to actually be 4-bytes in the FDE.

for non-intel and non-amd X86 CPUs it is right (VIA, etc.).

c4174d675b Using _MSC_VER there was wrong, better just use the already existing ifdefs for 
x86 CPU detection for the X86 getHostCPUName too, and create a simple
getHostCPUName that returns "generic" for all else.
