[mips] Disable tail calls temporarily Disable tail calls while the remaining bugs are fixed. Enable only for tests. Reviewers: vkalintiris Differential Review: https://reviews.llvm.org/D24912 llvm-svn: 282487

[mips] Correct tail call encoding for MIPSR6 r277708 enabled tails calls for MIPS but used the 'jr' instruction when the jump target was held in a register. For MIPSR6, 'jalr $zero, $reg' should have been used. Additionally, add missing patterns for external and global symbols for tail calls.

[mips] Restrict tail call optimization The tail call optimization was being used without proper consideration of ABI requirements for saving and restoring the GP.
