DW_OP_const <const> doesn't describe a constant value, but a value at a constant address.
The proper way to describe a constant value is DW_OP_constu <const>, DW_OP_stack_value.
Added DW_OP_stack_value to the stack.

getLVForNamespaceScopeDecl believed that it wasn't possible for it to
ever see an IndirectFieldDecl. However, this can occur when determining
whether or not something is a redeclaration of a member of an anonymous
static union.
This fixes PR21858.

The dead code elimination is a pass that looks very promising, but needs some
more compile-time tuning before enabling it by default seems sensible.

These methods are only used by MCJIT and are very specific to it. In fact, they
are also fairly specific to the fact that we have a dynamic linker of
relocatable objects.

Some targets like microMIPS and ARM Thumb use the last bit of a symbol's
value to mark 'compressed' code. This patch adds new virtual function
`DynamicTable::getAtomVirtualAddress` which allows to adjust a symbol's
value before using it in a dynamic table tags like DT_INIT / DT_FINI.

In the large code model we have to first get the address of the GOT entry, load
the address of the constant, and then load the constant itself.
To avoid these loads and the GOT entry alltogether this commit changes the way
how FP constants are materialized in the large code model. The constats are now
materialized in a GPR and then bitconverted/moved into the FPR.

Add patterns to match SSE (shufpd) and AVX (vpermilpd) shuffle codegen
when storing the high element of a v2f64. The existing patterns were
only checking for an unpckh type of shuffle.

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.

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.

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.

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.
