Alex Zinenko 74628c4305 [mlir] Add Python bindings for AffineExpr 
This adds the Python bindings for AffineExpr and a couple of utility functions
to the C API. AffineExpr is a top-level context-owned object and is modeled
similarly to attributes and types. It is required, e.g., to build layout maps
of the built-in memref type.

Stella Laurenzo 62195b7548 [mlir][CAPI] Convert the rest of the API int -> bool. 
* Follows on https://reviews.llvm.org/D92193
* I had a mid-air collision with some additional occurrences and then noticed that there were a lot more. Think I got them all.

Mehdi Amini c7994bd939 Switch from C-style comments `/* ... */` to C++ style `//` (NFC) 
This is mostly a scripted update, it may not be perfect.

function replace() {
  FROM=$1
  TO=$2
  git grep "$FROM" $REPO_PATH |cut -f 1 -d : | sort -u | \
    while read file; do
      sed -i "s#$FROM#$TO#" $file ;
    done
}

replace '|\*===----------------------------------------------------------------------===\*|$' '//===----------------------------------------------------------------------===//'
replace '^/\* =' '//=='
replace '^/\*=' '//='
replace '^\\\*=' '//='
replace '^|\*' '//'
replace ' \*|$' ''
replace '=\*\\$' '=//'
replace '== \*/$' '===//'
replace '==\*/$' '==//'
replace '^/\*\*\(.*\)\*/$' '///\1'
replace '^/\*\(.*\)\*/$' '//\1'
replace '//============================================================================//' '//===----------------------------------------------------------------------===//'

Mehdi Amini b4fa6d3e13 Switch the CallbackOstream wrapper in the MLIR C API to an Unbuffered stream 
This delegate the control of the buffering to the user of the API. This
seems like a safer option as messages are immediately propagated to the
user, which may lead to less surprising behavior during debugging for
instance.
In terms of performance, a user can add a buffered stream on the other
side of the callback.
