x86: Replace ia32 with x86 when referring to the generic architecture

ia32 implies 32bit, while these files provide descriptions for IA32,
X86_64, and X32 architectures. The term "x86" fits this used better
without resorting to using the term "Intel" which isn't quite right as
it excludes things like the tune-c3 file describing a Via CPU.
