b9ca1af69e Don't touch r11 in __tls_get_addr stub
This modifies the special __tls_get_addr stub that checks for a
tlsdesc style __tls_index entry and returns early.  Not using r11
isn't much benefit at the moment but a followup patch will preserve
regs around the first call to __tls_get_addr when the __tls_index
entry isn't yet set up for an early return.

c3614cffc8 PowerPC TLS tests
This patch adds some --no-tls-optimize tests and performs some of the
existing dynamic tests with tls markers in order to catch any
regression in PLT counting.
