21ed78f564 [mips][mips64r6] b(ge|lt)zal are not available on MIPS32r6/MIPS64r6 and bal is a normal instruction
Summary:
b(ge|lt)zal have been removed in MIPS32r6/MIPS64r6. However, bal (an alias
for 'bgezal $zero, $offset') still remains with the same encoding it had
prior to MIPS32r6/MIPS64r6.

Updated the MipsNaCLELFStreamer, and MipsLongBranch to correctly handle the
MIPS32r6/MIPS64r6 BAL instruction in addition to the existing BAL_BR pseudo.

No changes were required to the CodeGen test that looks for BAL
(test/CodeGen/Mips/longbranch.ll) since the new instruction has the same
syntax.

28002c2f82 [mips][mips64r6] [sl][duw]xc1 are not available on MIPS32r6/MIPS64r6
Summary:
Folded mips64-fp-indexed-ls.ll into fp-indexed-ls.ll. To do so, the zext's in
mips64-fp-indexed-ls.ll were changed to implicit sign extensions (performed
by getelementptr). This does not affect the purpose of the test.

Depends on D4004
