Remove the assert()'s from the LLVMCreateDisasmCPU() library API and just
return 0 to indicate failure to create the disassembler. A library routine
should not assert and just let the caller handler the error. For example
darwin's otool(1) will simply print an error if it ends up using a library
that is not configured for a target it wants:
% otool -tv ViewController.o
ViewController.o:

can't create arm llvm disassembler
This is much better than an abort which appears as a crash to the user or
even the assert when using a Debug+Asserts built library:

Add a doFinalization method to the DataLayout pass.
This pass is meant to be immutable, however it holds mutable state to cache StructLayouts.
This method will allow the pass manager to clear the mutable state between runs.
Note that unfortunately it is still necessary to have the destructor, even though it does the
same thing as doFinalization. This is because most TargetMachines embed a DataLayout on which
doFinalization isn't run as its never added to the pass manager.
I also didn't think it was necessary to complication things with a deInit method for which
doFinalization and ~DataLayout both call as there's only one field of mutable state. If we had
more fields to finalize i'd have added this.

LibCallSimplifier: optimize speed for short-lived instances
Nadav reported a performance regression due to the work I did to
merge the library call simplifier into instcombine [1]. The issue
is that a new LibCallSimplifier object is being created whenever
InstCombiner::runOnFunction is called. Every time a LibCallSimplifier
object is used to optimize a call it creates a hash table to map from
a function name to an object that optimizes functions of that name.
For short-lived LibCallSimplifier instances this is quite inefficient.
Especially for cases where no calls are actually simplified.
This patch fixes the issue by dropping the hash table and implementing
an explicit lookup function to correlate the function name to the object
that optimizes functions of that name. This avoids the cost of always
building and destroying the hash table in cases where the LibCallSimplifier
object is short-lived and avoids the cost of building the table when no
simplifications are actually preformed.
On a benchmark containing 100,000 calls where none of them are simplified
I noticed a 30% speedup. On a benchmark containing 100,000 calls where
all of them are simplified I noticed an 8% speedup.

Remove support for versioned debug info.
Versioned debug info support has been a burden to maintain & also compromised
current debug info verification by causing test cases testing old debug info to
remain rather than being updated to the latest. It also makes it hard to add or
change the metadata schema by requiring various backwards-compatibility in the
DI* hierarchy.
So it's being removed in preparation for new changes to the schema to tidy up
old/unnecessary fields and add new fields needed for new debug info (well, new
to LLVM at least).
The more surprising part of this is the changes to DI*::Verify - this became
necessary due to the changes to AsmWriter. AsmWriter was relying on the version
test to decide which bits of metadata were actually debug info when printing
the comment annotations. Without the version information the tag numbers were
too common & it would print debug info on random metadata that happened to
start with an integer that matched a tag number. Instead this change makes the
Verify functions more precise (just adding "number of operands" checks - not
type checking those operands yet) & relies on that to decide which metadata is
debug info metadata.

Revert r176154 in favor of a better approach.
Code generation makes some basic assumptions about the IR it's been given. In
particular, if there is only one 'invoke' in the function, then that invoke
won't be going away. However, with the advent of the `llvm.donothing' intrinsic,
those invokes may go away. If all of them go away, the landing pad no longer has
any users. This confuses the back-end, which asserts.
This happens with SjLj exceptions, because that's the model that modifies the IR
based on there being invokes, etc. in the function.
Remove any invokes of `llvm.donothing' during SjLj EH preparation. This will
give us a CFG that the back-end won't be confused about. If all of the invokes
in a function are removed, then the SjLj EH prepare pass won't insert the bogus
code the relies upon the invokes being there.
