x86: Update segment register check in Intel syntax
https://sourceware.org/ml/binutils/2009-04/msg00223.html
introduced a new Intel syntax parser which accepts
mov eax, fs:gs:[eax]
It ignores anything between ':'s after fs and treats
mov eax, DWORD PTR fs:foobar:16
mov eax, DWORD PTR fs:foobar:barfoo:16
mov eax, DWORD PTR fs:ds:16
mov eax, DWORD PTR fs:ds:cs:16
as
mov eax, DWORD PTR fs:16
This patch updates segment register check and only allows a single ':'.
