This commit fixes a regression (from LLVM 10 to LLVM 11 RC3) in the LLVM
C API.
Previously, commit 1ee6ec2bf removed the mask operand from the
ShuffleVector instruction, storing the mask data separately in the
instruction instead; this reduced the number of operands of
ShuffleVector from 3 to 2. AFAICT, this change unintentionally caused
a regression in the LLVM C API. Specifically, it is no longer possible
to get the mask of a ShuffleVector instruction through the C API. This
patch introduces new functions which together allow a C API user to get
the mask of a ShuffleVector instruction, restoring the functionality
which was previously available through LLVMGetOperand().
This patch also adds tests for this change to the llvm-c-test
executable, which involved adding support for InsertElement,
ExtractElement, and ShuffleVector itself (as well as constant vectors)
to echo.cpp. Previously, vector operations weren't tested at all in
echo.ll.
I also fixed some typos in comments and help-text nearby these changes,
which I happened to spot while developing this patch. Since the typo
fixes are technically unrelated other than being in the same files, I'm
happy to take them out if you'd rather they not be included in the patch.

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.

These include:
* Several functions for creating an LLVMDIBuilder,
* LLVMDIBuilderCreateCompileUnit,
* LLVMDIBuilderCreateFile,
* LLVMDIBuilderCreateDebugLocation.

This makes it less likely to clash with other stuff that might be linked
in by change, e.g. ncurses exposes an external function called simply
"echo", so linking ncurses statically into the binary explodes in funny
ways.

Summary:
This basically add an echo test case in C. The support is limited right now, but full support would just be too much to review at once.
The echo test case simply get a module as input and try to output the same exact module. This allow to check the both reading and writing API are working as expected.
I want to improve this test over time to support more and more of the API, in order to improve coverage (coverage is quite poor right now).
Test Plan: Run the test.

This deprecates:
* LLVMParseBitcode
* LLVMParseBitcodeInContext
* LLVMGetBitcodeModuleInContext
* LLVMGetBitcodeModule
They are replaced with the functions with a 2 suffix which do not record
a diagnostic.

Summary:
MetadataAsValue uses a canonical format that strips the MDNode if it
contains only a single constant value. This triggers an assertion when
trying to cast the value to a MDNode.

Read bytecode from stdin - list summary of globals
* --targets-list
List available targets
* --object-list-sections
Read object file from stdin - list sections
* --object-list-symbols
Read object file from stdin - list symbols (like nm)
