[build] Allow __asmcall to be used as a type attribute

The "used" attribute can be applied only to functions or variables,
which prevents the use of __asmcall as a type attribute.

Fix by removing "used" from the definition of __asmcall for i386 and
x86_64 architectures, and adding explicit __used annotations where
necessary.
