This change implements the TLS extension to the x86 ABI. This allows threads to have thread-private data which is quickly accessible via a segment in the GDT, stored in %gs. The patch implements the relevent syscalls (setthreadarea), and also manages switching the VCPU's segment information at thread context-switch time. Mostly Tom Hughes' work. git-svn-id: svn://svn.valgrind.org/valgrind/trunk@2215 a5019735-40e9-0310-863c-91ae7b9d1cf9
