Rollup merge of #56349 - davidtwco:issue-55396-inference-extension, r=nagisa 
rustc 1.30.0's linker flavor inference is a non-backwards compat change to -Clinker

Part of #55396.

This commit modifies linker flavor inference to only remove the extension
to the linker when performing inference if that extension is a 'exe'.

d8190afbcb Fix alignment of stores to scalar pair 
The alignment for the second element of a scalar pair is not the
same as for the first element. Make sure it is computed correctly
based on the element size.

cc9c91d385 Pass --export-dynamic to LLD for wasm

c86b1529a5 wasm: Pass --no-demangle to LLD 
Our mangling scheme is not C++'s, so tell LLD to not demangle anything
so we can handle Rust-specific demangling ourselves.

Cleanup from lexical MIR borrowck removal

Lexical MIR borrowck was removed months ago now, and `EndRegion`s are no longer used for MIRI verification.

* Remove `rustc::mir::StatementKind::EndRegion` and the `-Zemit_end_regions` flag
* Use `RegionVid` instead of `Region` in BorrowSet
* Rewrite drop generation to create fewer goto terminators.

6a2d1b4e15 Auto merge of #54071 - eddyb:alignsssss, r=oli-obk 
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).
