[Mips] Remove "single" from the list of valid MIPS float ABI names. Add
two new options –msingle-float and –mdouble-float. These options can be
used simultaneously with float ABI selection options (-mfloat-abi,
-mhard-float, -msoft-float). They mark whether a floating-point
coprocessor supports double-precision operations.

Handle incompatible redeclarations of library builtins better.
Invalid redeclarations of valid explicit declarations shouldn't
take the same path as redeclarations of implicit declarations,
and invalid local extern declarations shouldn't foul things up
for everybody else.

[Mips] Follow-up to r179481. Consider "single-float" as a separate
independent of float ABI feature in the MipsTargetInfoBase class.

AddTargetFeature() routine to handle -msingle-float / -mdouble-float
options.

CodeGen support for function-local static thread_local variables with
non-constant constructors or non-trivial destructors. Plus bugfixes for
thread_local references bound to temporaries (the temporaries themselves are
lifetime-extended to become thread_local), and the corresponding case for
std::initializer_list.
