tcg/arm: remove SAVE_LR code

There is no need to save the LR register (r14) before a call to a
subroutine. According to the "Procedure Call Standard for the ARM
Architecture", it is the job of the callee to save this register.
Moreover, this register is already saved in the prologue/epilogue.

This patch removes the disabled SAVE_LR code, as there is no need to
reenable later.
