[CMake] Workflow improvements to PGO generation
This patch adds a few new convenience options used by the PGO CMake cache to setup options on bootstrap stages. The new options are:
PGO_INSTRUMENT_LTO - Builds the instrumented and final builds with LTO
PGO_BUILD_CONFIGURATION - Accepts a CMake cache script that can be used for complex configuration of the stage2-instrumented and stage2 builds.
The patch also includes a fix for bootstrap dependencies so that the instrumented LTO tools don't get used when building the final stage, and it adds distribution targets to the passthrough.

Emit debug info for dynamic classes if they are imported from a DLL.
With -debug-info-kind=limited, we omit debug info for dynamic classes that live in other TUs. This reduces duplicate type information. When statically linked, the type information comes together. But if your binary has a class derived from a base in a DLL, the base class info is not available to the debugger.
The decision is made in shouldOmitDefinition (CGDebugInfo.cpp). Per a suggestion from rnk, I've tweaked the decision so that we do include definitions for classes marked as DLL imports. This should be a relatively small number of classes, so we don't pay a large price for duplication of the type info, yet it should cover most cases on Windows.
Essentially this makes debug info for DLLs independent, but we still assume that all TUs within the same DLL will be consistently built with (or without) debug info and the debugger will be able to search across the debug info within that scope to resolve any declarations into definitions, etc.

Summary:
This is part of a serious of patches to evolve ADCE.cpp to support
removing of unnecessary control flow.
This patch changes the data structures to hold liveness information to
support the additional information we will eventually need. In
particular we now have a notion of basic blocks being live because
they contain a live operations. This will eventually feed into control
dependence analysis of which branches are live. We cater to getting
from instructions to associated block information and from blocks to
information about their terminators.
This patch also changes the structure of the main loop of the
algorithm so that it alternates propagating liveness between
instructions and usign control dependence information to mark branches
live.
We force all terminators live for now until we add code to handlinge
removing control flow in a later patch.

[ScopInfo] Make scalars used by PHIs in non-affine regions available
Normally this is ensured when adding PHI nodes, but as PHI node dependences
do not need to be added in case all incoming blocks are within the same
non-affine region, this was missed.
This corrects an issue visible in LNT's sqlite3, in case invariant load hoisting
was disabled.

[Thumb] Validate branch target for CBZ/CBNZ instructions.
Summary:
The assembler currently does not check the branch target for CBZ/CBNZ
instructions, which only permit branching forwards with a positive offset. This
adds validation for the branch target to ensure negative PC-relative offsets are
not encoded into the instruction, whether specified as a literal or as an
assembler symbol.

able to use operator[] on the StringMap.
