Ivan Krysak e62d4f79ef ABI: remove an obsolete definition parameter
Since pointer to copy system got straightenned up, the old way of
marking them (`abi::Definition::UsePointerToCopyForStackArguments`)
is no longer needed.

Ivan Krysak 94b6be25ae ABI-tests: check equivalence after compatibility
This does not change anything about the "successful" tests, but does
make "failing" ones slightly easier to debug - since "compatibility"
failures are generally easier to work with (they provide more explicit
information about the failure) that "equivalence" ones.

Djordje Todorovic 79460c6933 PDBImport: Handle forward referenced types
A class or a struct type A can be a forward declaration and refer
to another type B in PDB, so we need to follow the references.
We pre-create type for B, when we face type A, and then, when we
visit type B, we populate the fields for the model::type we
pre-created.

In addition, this patch fixes some minor/side bugs:
  - Handle SHORT/Int16Short simple type
  - Do not delete model::Function if Prototype is invalid.

Each model::Segment is associated to a model::StructType. Now we also
create sub-`structs` for sections, if available.

Ivan Krysak 386cb26f6d ABI: introduce a new ABI configuration option
It's called `AllowUnnaturallyAlignedTypesInRegisters` and explicitly
allows weirdly aligned structs in registers.

Alessandro Di Federico a3a549be48 EnforceABI step: reduce work done by InlineHelpers
InlineHelpers often inlines functions that contain a switch on an
argument that is constant on the call site. Specifically, this is true
for the `cc_compute_c` and `cc_compute_all` helpers of x86
architectures. The LLVM inliner, in such situations, is smart and
inlines a reduced amount of code, significantly reducing the maximum
size of the modules we work with.

However, before this commit, we couldn't capture this fact due to
`newpc` preventing constant propagation of the values of CSV set in an
instruction into their usage in the next instruction.

Running `PromoteCSV` before `InlineHelpers`, along with `mem2reg`
enables us to capture this behavior effectively.
