Raphael Isemann 5ffd940ac0 Reland [FileCheck] Move FileCheck implementation out of LLVMSupport into its own library
This relands e9a3d1a401 which was originally
missing linking LLVMSupport into LLMVFileCheck which broke the SHARED_LIBS build.

Original summary:

The actual FileCheck logic seems to be implemented in LLVMSupport. I don't see a
good reason for having FileCheck implemented there as it has a very specific use
while LLVMSupport is a dependency of pretty much every LLVM tool there is. In
fact, the only use of FileCheck I could find (outside the FileCheck tool and the
FileCheck unit test) is a single call in GISelMITest.h.

This moves the FileCheck logic to its own LLVMFileCheck library. This way only
FileCheck and the GlobalISelTests now have a dependency on this code.

This patch adds tests for dumping the .debug_line_str section. The
dumper of the debug_line_str section is able to write nonprintable
strings as escaped chars while the dumper of the debug_str and
debug_str.dwo sections cannot. I will fix them and add tests for them

Georgii Rymar ca233be2f0 [llvm-readobj][test] - Remove amdgpu-elf-definitions.test
`amdgpu-elf-definitions.test` is a file that tests
`Format`, 'OS/ABI' and 'Machine' fields printed for EM_AMDGPU.
It uses a precompiled object.

It is not needed to have it, because:
1) We already test formats in `file-header-format.test` + `llvm/unittests/Object/ELFObjectFileTest.cpp`.
2) We test 'OS/ABI' in `file-header-os-abi.test` for all possible values.
3) We test machine types in `file-header-machine-types.test`

In addition we have `amdgpu-elf-headers.test` which tests EM_AMDGPU specific flags. I.e.
it also tests the fact that llvm-readobj/elf are able to dump such objects.

This patch removes the test case and the corresponding binary.

I have fixed up a number of warnings resulting from TypeSize -> uint64_t

think most of the changes are fairly trivial except for those in

the MachineMemoryOperands in a sensible way for scalable vectors.

I have added a CHECK line to the following test:

Petr Hosek 3c7bfbd683 [CMake] Use find_library for ncurses
Currently it is hard to avoid having LLVM link to the system install of
ncurses, since it uses check_library_exists to find e.g. libtinfo and
not find_library or find_package.

With this change the ncurses lib is found with find_library, which also
considers CMAKE_PREFIX_PATH. This solves an issue for the spack package
manager, where we want to use the zlib installed by spack, and spack
provides the CMAKE_PREFIX_PATH for it.

This is a similar change as https://reviews.llvm.org/D79219, which just
landed in master.

Christopher Tetreault 867de151a5 [SVE] Mark VectorType::getNumElements() deprecated
getNumElements() is being removed from base VectorType in
order to eliminate the class of bugs in which a scalable vector
is accidentally treated like a fixed length vector. Clients of
this function should either call getElementCount(), and handle
the case where getElementCount().isScalable() is true, or they can
cast to FixedVectorType and call getNumElements() if they are
sure that the vector has fixed width.

Deprecated VectorType functions will be removed after the LLVM
12 branch.

River Riddle 88c6e25e4f [mlir][OpFormatGen] Add support for specifiy "custom" directives.
This revision adds support for custom directives to the declarative assembly format. This allows for users to use C++ for printing and parsing subsections of an otherwise declaratively specified format. The custom directive is structured as follows:

```
custom-directive ::= `custom` `<` UserDirective `>` `(` Params `)`
```

`user-directive` is used as a suffix when this directive is used during printing and parsing. When parsing, `parseUserDirective` will be invoked. When printing, `printUserDirective` will be invoked. The first parameter to these methods must be a reference to either the OpAsmParser, or OpAsmPrinter. The type of rest of the parameters is dependent on the `Params` specified in the assembly format.

As discussed in D86798 / rG09652721 , we were potentially
returning a different result for whether an Instruction

derived class method.

This requires relaxing asserts in GVN, but that pass
seems to be working otherwise.

NewGVN requires more work because it uses different
code paths for numbering binops and calls.
