data. This diff implements a flow-based algorithm, called profi, that helps to
overcome the inaccuracies in a profile after it is collected.

Profi is an extended and significantly re-engineered classic MCMF (min-cost
max-flow) approach suggested by Levin, Newman, and Haber [2008, Complementing
missing and inaccurate profiling using a minimum cost circulation algorithm]. It
models profile inference as an optimization problem on a control-flow graph with
the objectives and constraints capturing the desired properties of profile data.
Three important challenges that are being solved by profi:
- "fixing" errors in profiles caused by sampling;
- converting basic block counts to edge frequencies (branch probabilities);
- dealing with "dangling" blocks having no samples in the profile.

The worst-time complexity is quadratic in the number of blocks in a function,
O(|V|^2). However a careful engineering and extensive evaluation shows that
the running time is (slightly) super-linear. In particular, instances with
1000 blocks are solved within 0.1 second.

The algorithm has been extensively tested internally on prod workloads,
significantly improving the quality of generated profile data and providing
speedups in the range from 0% to 5%. For "smaller" benchmarks (SPEC06/17), it
generally improves the performance (with a few outliers) but extra work in

[lldb] Fix lookup for global constants in namespaces

LLDB uses mangled name to construct a fully qualified name for global
variables. Sometimes DW_TAG_linkage_name attribute is missing from
debug info, so LLDB has to rely on parent entries to construct the
fully qualified name.

Currently, the fallback is handled when the parent DW_TAG is either
DW_TAG_compiled_unit or DW_TAG_partial_unit, which may not work well
for global constants in namespaces. For example:

  namespace ns {
    const int x = 10;
  }

may produce the following debug info:

  <1><2a>: Abbrev Number: 2 (DW_TAG_namespace)
     <2b>   DW_AT_name        : (indirect string, offset: 0x5e): ns
  <2><2f>: Abbrev Number: 3 (DW_TAG_variable)
     <30>   DW_AT_name        : (indirect string, offset: 0x61): x
     <34>   DW_AT_type        : <0x3c>
     <38>   DW_AT_decl_file   : 1
     <39>   DW_AT_decl_line   : 2
     <3a>   DW_AT_const_value : 10

Since the fallback didn't handle the case when parent tag is
DW_TAG_namespace, LLDB wasn't able to match the variable by its fully
qualified name "ns::x". This change fixes this by additional check
if the parent is a DW_TAG_namespace.

[mlir][memref] Fix expanded shape ops memref.cast folding with changed type

`memref.expand_shape` has verification logic to make sure
result dim must be static if all the collapsing src dims are static.

This can be relaxed once expand_shape supports more dynamism.
