[Symbolizer][WebAssembly] Use wasm-specific getSymbolSize (#82083)
getSymbolSize was recently added to WasmObjectFile and has correct sizes
for most symbol types. This makes llvm-symbolizer correctly symbolize
addresses in the middle of the symbol.
When reworking the test I also noticed that the DWARF info seems to be
wrong for the first instruction in each function. I noted that in the test
comments but didn't attempt to fix here.

[XCOFF][OBJECT] get symbol size by calling XCOFF interfaces (#67304)
Computing the symbol size as the gap between sorted symbols are not
right for XCOFF.
For XCOFF, the size info is stored in aux symbol and can be got from
existing XCOFF interface `getSymbolSize()`.
This patch changes XCOFFObjectFile to call this API to get sizes for
symbols.

[SymbolSize] Improve the performance of SymbolSize computation
The current algorithm to compute the symbol size is quadratic if there
are lots of symbols sharing the same addresses. This happens in a debug
build when lots of debug symbols get emitted in the symtab.
This patch improves the performance like `llvm-symbolizer` that relies
on the symbol size computation. Symbolizing a release+assert clang with
DebugInfo sees significant improvements from 3:40min to less than 1s.

[WebAssembly] Add WebAssembly support to llvm-symbolizer
The only thing missing for basic llvm-symbolizer support is the ability on

Also, when the WasmAsmParser switches sections on new functions, also add the
section to the list of Dwarf sections if Dwarf is being generated for assembly;
this allows writing of simple tests.

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.

Fix computeSymbolSizes SEGFAULT on invalid file
We use llvm-symbolizer in some production systems, and we run it
against all possibly related files, including some that are not
ELF. We noticed that for some of those invalid files, llvm-symbolizer
would crash with SEGFAULT. Here is an example of such a file.
It is due to that in computeSymbolSizes, a loop uses condition
for (unsigned I = 0, N = Addresses.size() - 1; I < N; ++I) {
where if Addresses.size() is 0, N would overflow and causing the loop
to access invalid memory.
Instead of patching the loop conditions, the commit makes so that the
function returns early if Addresses is empty.
Validated by checking that llvm-symbolizer no longer crashes.
Patch by Teng Qin!

Change how symbol sizes are handled in lib/Object.
COFF and MachO only define symbol sizes for common symbols. Reflect that
in the class hierarchy by having a method for common symbols only in the base
and a general one in ELF.
This avoids the need of using a magic value for the size, which had a few
problems
* Most callers didn't check for it.
* The ones that did could not tell the magic value from a file actually having
that value.
