Others ports have them though, for example i386, ARM and SPARC.

Hi Segher,
CSE does not consider calls, not even const calls. This patch puts a
REG_EQUAL note on the pseudo we assign the __tls_get_addr result to,
so that those pseudos can be CSE'd and the extra calls deleted as dead
code.
CSE should really handle const calls directly, but it is stage 4.
Tested on
