  1. [NFC][SimplifyCFG] 'Safely extract low bits' pattern will also benefi… 

    …t from -phi-node-folding-threshold=3

This is the naive implementation of x86 BZHI/BEXTR instruction:
it takes input and bit count, and extracts low nbits up to bit width.
I.e. unlike shift it does not have any UB when nbits >= bitwidth.
Which means we don't need a while PHI here, simple select will do.
And if it's a select, it should then be trivial to fix codegen
to select it to BEXTR/BZHI.

  4. Remove DWARFExpression::LocationListSize 

    Summary:
The only reason for this function's existance is so that we could pass
the correct size into the DWARFExpression constructor. However, there is
no harm in passing the entire data extractor into the DWARFExpression,
since the same code is performing the size determination as well as the
subsequent parse. So, if we get malformed input or there's a bug in the
parser, we'd compute the wrong size anyway.

Additionally, reducing the number of entry points into the location list
parsing machinery makes it easier to switch the llvm debug_loc(lists)
parsers.

While inside, I added a couple of tests for invalid location list
handling.

  5. Fix GetDIEForDeclContext so it only returns entries matching the prov… 

    …ided context

Currently, we return all the entries such that their decl_ctx pointer >= decl_ctx provided.
Instead, we should return only the ones that decl_ctx pointer == decl_ctx provided.
