assembly to reproduce abort

Here's a second test case with a different missing opcode.

MONO_PATH=/opt/mono/lib/moonlight/plugin/ gdb --args mono --security=core-clr
--compile-all System.Xml.sigabrt.56962.dll

** ERROR **: Opcode 'float_conv_to_ovf_u_un' missing from machine description
file.
aborting...

Program received signal SIGABRT, Aborted.
