e0246a9536 llvm-symbolizer: Add a FRAME command.
This command prints a description of the referenced function's stack frame.
For each formal parameter and local variable, the tool prints:

- function name
- variable name
- file/line of declaration
- FP-relative variable location (if available)
- size in bytes
- HWASAN tag offset

This information will be used by the HWASAN runtime to identify local
variables in UAR reports.

10ceb1aee9 [llvm-symbolizer] Add --output-style switch.
In general, llvm-symbolizer follows the output style of GNU's addr2line.
However, there are still some differences; in particular, for a requested
address, llvm-symbolizer prints line and column, while addr2line prints
only the line number.

This patch adds a new switch to select the preferred style.

24470819e8 [llvm-symbolizer] Add support for --basenames/-s
This fixes https://bugs.llvm.org/show_bug.cgi?id=40068.

--basenames is a GNU addr2line switch which strips the directory names
from the file path in the output.

6b547686c5 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.

4ee57e2bef Get function start line number from DWARF info
DWARF info contains info about the line number at which a function starts (DW_AT_decl_line).

This patch creates a function to look up the start line number for a function, and returns it in
DILineInfo when looking up debug info for a particular address.
