54215e5d31 [BlockExtractor] Avoid assert with wrong line format
Summary:
When the line format is wrong, we may end up accessing out of bound
memory. eg: the test with invalide line will cause assert.
Assertion `idx < size()' failed

The fix is to report fatal when we found mismatched line format.

8cc4cdc71a [BlockExtractor] Change the basic block separator from ',' to ';'
This change aims at making the file format be compatible with the
way LLVM handles command line options.

ba46ee9157 [BlockExtractor] Extend the file format to support the grouping of basic blocks
Prior to this patch, each basic block listed in the extrack-blocks-file
would be extracted to a different function.

This patch adds the support for comma separated list of basic blocks
to form group.

When the region formed by a group is not extractable, e.g., not single
entry, all the blocks of that group are left untouched.

Let us see this new format in action (comments are not part of the
file format):
;; funcName bbName[,bbName...]
   foo      bb1        ;; Extract bb1 in its own function
   foo      bb2,bb3    ;; Extract bb2,bb3 in their own function
   bar      bb1,bb4    ;; Extract bb1,bb4 in their own function
   bar      bb2        ;; Extract bb2 in its own function

Assuming all regions are extractable, this will create one function and
thus one call per region.

ae65e281f3 Update the file headers across all of the LLVM projects in the monorepo
to reflect the new license.

We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.

Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

9667127c14 Rename DEBUG macro to LLVM_DEBUG.
The DEBUG() macro is very generic so it might clash with other projects.
The renaming was done as follows:
- git grep -l 'DEBUG' | xargs sed -i 's/\bDEBUG\s\?(/LLVM_DEBUG(/g'
- git diff -U0 master | ../clang/tools/clang-format/clang-format-diff.py -i -p1 -style LLVM
- Manual change to APInt
- Manually chage DOCS as regex doesn't match it.

In the transition period the DEBUG() macro is still present and aliased
to the LLVM_DEBUG() one.

e71a34b01d BlockExtractor: Don’t delete functions directly
Blocks may have function calls, so don’t erase functions
directly to avoid erasing a function that has a user.

4c29cfd3e4 [llvm-extract] Support extracting basic blocks
Summary:
Currently, there is no way to extract a basic block from a function easily. This patch
extends llvm-extract to extract the specified basic block(s).
