Rollup merge of #58717 - hellow554:nonzero_parse, r=oli-obk 
Add FromStr impl for NonZero types

This is a WIP implementation because I do have some questions regarding the solution.

Somebody should ping the lang team on this I guess.
Please see the annotations on the code for more details.

Closes #58604

8d3dd39d88 Correct minimum system LLVM version in tests 
Since commit 9452a8dfa3, the new debug info format is only generated
for LLVM 8 and newer versions. However, the tests still assume that LLVM
7 will use the new debug info format. Fix the tests (and a comment in
the code) to match the actual version check.

Rename variadic to c_variadic 
Function signatures with the `variadic` member set are actually
C-variadic functions. Make this a little more explicit by renaming the
`variadic` boolean value, `c_variadic`.

df0466d0bb Rebase to the llvm-project monorepo 
The new git submodule src/llvm-project is a monorepo replacing src/llvm
and src/tools/{clang,lld,lldb}.  This also serves as a rebase for these
projects to the new 8.x branch from trunk.

The src/llvm-emscripten fork is unchanged for now.

1c95f5a34c Fix issue 57762 
Issue 57762 points out a compiler crash when the compiler was built
using a stock LLVM 7.  LLVM 7 was released without a necessary fix for
a bug in the DWARF discriminant code.

This patch changes rustc to use the fallback mode on (non-Rust) LLVM 7.

Closes #57762

Add template parameter debuginfo to generic types

This changes debuginfo generation to add template parameters to
generic types.  With this change the DWARF now has
DW_TAG_template_type_param for types, not just for functions, like:

 <2><40d>: Abbrev Number: 6 (DW_TAG_structure_type)
    <40e>   DW_AT_name        : (indirect string, offset: 0x375): Generic<i32>
    <412>   DW_AT_byte_size   : 4
    <413>   DW_AT_alignment   : 4
...
 <3><41f>: Abbrev Number: 8 (DW_TAG_template_type_param)
    <420>   DW_AT_type        : <0x42a>
    <424>   DW_AT_name        : (indirect string, offset: 0xa65e): T

rustc_target: separate out an individual alignment quantity type from Align.

Before this PR, `rustc_target::abi::Align` combined "power-of-two alignment quantity" semantics, with a distinction between ABI (required) and preferred alignment (by having two quantities).

After this PR, `Align` is only *one* such quantity, and a new `AbiAndPrefAlign` type is introduced to hold the pair of ABI and preferred `Align` quantities.

`Align` is used everywhere one quantity is necessary/sufficient, simplifying some of the code in codegen/miri, while `AbiAndPrefAlign` only in layout computation (to propagate preferred alignment).
