ARM: convert isTargetIOS checks to isTargetDarwin.
The distinction is mostly useful in the front-end. By the time we get here,
there are very few situations where we actually want different behaviour for
Darwin and IOS (in fact Darwin mostly just exists in a few tests). So this
should reduce any surprising weirdness for anyone using it.

[PowerPC] Implement BuildSDIVPow2, lower i64 pow2 sdiv using sradi
PPCISelDAGToDAG contained existing code to lower i32 sdiv by a power-of-2 using
srawi/addze, but did not implement the i64 case. DAGCombine now contains a
callback specifically designed for this purpose (BuildSDIVPow2), and part of
the logic has been moved to an implementation of that callback. Doing this
lowering using BuildSDIVPow2 likely does not matter, compared to handling
everything in PPCISelDAGToDAG, for the positive divisor case, but the negative
divisor case, which generates an additional negation, can potentially benefit
from additional folding from DAGCombine. Now, both the i32 and the i64 cases
have been implemented.

Match new shuffle codegen for MOVHPD patterns
Add patterns to match SSE (shufpd) and AVX (vpermilpd) shuffle codegen
when storing the high element of a v2f64. The existing patterns were

[mips] Removing __SIZEOF_INT128__ macro for MIPS64
This is a temporary workaround while MIPS64 has not yet fully supported
128-bit integers. But declaration of int128 type is necessary even though
`__SIZEOF_INT128__` is undefined because c++ standard header files like
`limits` throw error message if `__int128` is not available.

[X86] Make a code path in EltsFromConsecutiveLoads work only on vectors it expects
EltsFromConsecutiveLoads was apparently only ever called for 128-bit vectors, and assumed this implicitly. r223518 started calling it for AVX-sized vectors, causing the code path that had this assumption to crash.
This adds a check to make this path fire only for 128-bit vectors.

[ELF] Make -init/-fini options compatible with the gnu linker
The LLD linker searches initializer and finalizer function names
and emits DT_INIT/DT_FINI dynamic table tags to point to these symbols.
The -init/-fini command line options override initializer ("_init") and
finalizer ("_fini") function names used by default.
Now the -init/-fini options do not affect .init_array/.fini_array
sections. The corresponding code has been removed.

ClangFunction: Fix destruction order of parser and execution unit
Fix PR21802 by correcting the destruction order of
`ClangExpressionParser` and `IRExecutionUnit` in `ClangFunction`. The
former has hooks into the latter -- i.e., `clang::CGDebugInfo` points at
the `LLVMContext` -- so it needs to be torn down first.
This was exposed by r223802 in LLVM, which started doing work in the
`CGDebugInfo` teardown.
