Summary:
If the same value is going to be vectorized several times in the same
tree entry, this entry is considered to be a gather entry and cost of
this gather is counter as cost of InsertElementInstrs for each gathered
value. But we can consider these elements as ShuffleInstr with
SK_PermuteSingle shuffle kind.

Analyzing problems which appear in scan-build results can be very
difficult, as after the launch no exact invocation is stored, and it's
super-hard to launch the debugger.
With this patch, the exact analyzer invocation appears in the footer,
and can be copied to debug/check reproducibility/etc.

The reinterpret cast to uint32_t to read the little-endian instructions 
will only work on a little endian system. Use ulittle32_t to always read
little-endian (AArch64 instructions are always little endian).

Rather than hardcode the pointerness of the `id` and `class` types,
handle them generically.  This allows for the template type
specialization of `remove_pointer<id>` which would look through the `id`
type and deal with the `objc_object` structure without the pointer.

We should (almost) never consider a device-side declaration to match a
library builtin functio.  Otherwise clang may ignore the implementation
provided by the CUDA headers and emit clang's idea of the builtin.

The language standard does not define a function with this name,
so it is part of the user's namespace. This change fixes a duplicate

In addition to that, make sure that there are no boolean vector types that
are associated with multiple register classes. Specifically, remove v32i1
and v64i1 from integer register classes. These types will correspond to
results of vector comparisons, and as such should belong to the vector
predicate class. Having them in scalar registers as well makes legalization
ambiguous.

Normally when llvm-as sees only debug info errors in LLVM assembly, it simply
drops the debug info and outputs a valid LLVM bitcode and returns 0.

There is a bug in LLVM verifier which incorrectly treats a debug info error
as non-debug info error, which causes llvm-as returns 1 even though llvm-as
can drop the invalid debug info and outputs a valid LLVM bitcode.

This patch fixes that.

[X86] Rewrite vXi1 element insertion by using a vXi1 scalar_to_vector and inserting into a vXi1 vector.

The existing code was already doing something very similar to subvector insertion so this allows us to remove the nearly duplicate code.

This patch is a little larger than it should be due to differences between the DQI handling between the two today.
