Ideally we would store the MultiClasses by value directly in the maps, but I had some trouble with that before and this at least fixes the leak.

This change moves the ownership and access of GCFunctionInfo (the object which describes the safepoints associated with a safepoint under GCRoot) to GCModuleInfo. Previously, this was owned by GCStrategy which was in turned owned by GCModuleInfo. This made GCStrategy module specific which is 'surprising' given it's name and other purposes.
There's a few more changes needed, but we're getting towards the point we can reuse GCStrategy for gc.statepoint as well.
p.s. The style of this code ends up being a mess. I was trying to move code around without otherwise changing much. Once I get the ownership structure rearranged, I will go through and fixup spacing, naming, comments etc.

While we would correctly handle asm("foo") and reject asm(L"bar"), we
weren't careful to handle cases where an ascii literal could be
concatenated with a wide literal.
This fixes PR21822.

Quite a major error here: the expansions for the Pseudos with and without
folded load were mixed up. Fortunately it only affects ARM-mode, when not using
movw/movt, on Darwin. I'm guessing no-one actually uses that combination.

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.
