[InstCombine] dropRedundantMaskingOfLeftShiftInput(): pat. c/d/e with mask (PR42563)
Summary:
If we have a pattern `(x & (-1 >> maskNbits)) << shiftNbits`,
we already know (have a fold) that will drop the `& (-1 >> maskNbits)`
mask iff `(shiftNbits-maskNbits) s>= 0` (i.e. `shiftNbits u>= maskNbits`).
So even if `(shiftNbits-maskNbits) s< 0`, we can still
fold, we will just need to apply a **constant** mask afterwards:
```
Name: c, normal+mask
%t0 = lshr i32 -1, C1
%t1 = and i32 %t0, %x
%r = shl i32 %t1, C2
=>
%n0 = shl i32 %x, C2
%n1 = i32 ((-(C2-C1))+32)
%n2 = zext i32 %n1 to i64
%n3 = lshr i64 -1, %n2
%n4 = trunc i64 %n3 to i32
%r = and i32 %n0, %n4

[InstCombine] dropRedundantMaskingOfLeftShiftInput(): pat. a/b with mask (PR42563)
Summary:
And this is **finally** the interesting part of that fold!
If we have a pattern `(x & (~(-1 << maskNbits))) << shiftNbits`,
we already know (have a fold) that will drop the `& (~(-1 << maskNbits))`
mask iff `(maskNbits+shiftNbits) u>= bitwidth(x)`.
But that is actually ignorant, there's more general fold here:
In this pattern, `(maskNbits+shiftNbits)` actually correlates
with the number of low bits that will remain in the final value.
So even if `(maskNbits+shiftNbits) u< bitwidth(x)`, we can still
fold, we will just need to apply a **constant** mask afterwards:
```
Name: a, normal+mask
%onebit = shl i32 -1, C1
%mask = xor i32 %onebit, -1
%masked = and i32 %mask, %x
%r = shl i32 %masked, C2
=>
%n0 = shl i32 %x, C2
%n1 = add i32 C1, C2
%n2 = zext i32 %n1 to i64
%n3 = shl i64 -1, %n2

[lldb] Fix that importing decls in a TagDecl end up in wrong declaration context (partly reverts D61333)
Summary:
In D61333 we dropped some code from ClangASTSource that checks if imported declarations
ended up in the right DeclContext. While this code wasn't tested by the test suite (or better, it was hit
by the test suite but we didn't have any checks that were affected) and the code seems pointless
(as usually Decls should end up in the right DeclContext), it actually broke the data formatters in LLDB
and causes a bunch of obscure bugs where structs suddenly miss all their members. The first report we got about
this was that printing a std::map doesn't work anymore when simply doing "expr m" (m is the std::map).
This patch reverts D61333 partly and reintroduces the check in a more stricter way (we actually check now that
we *move* the Decl and it is in a single DeclContext). This should fix all the problems we currently have until
we figure out how to properly fix the underlying issues. I changed the order of some std::map formatter tests
which is currently the most reliable way to test this problem (it's a tricky setup, see description below).
Fixes rdar://
55502701 and rdar://
55129537
--------------------------------------
Some more explanation what is actually going on and what is going wrong:
The situation we have is that if we have a `std::map m` and do a `expr m`, we end up seeing an empty map
(even if `m` has elements). The reason for this is that our data formatter sees that std::pair<int, int> has no
members. However, `frame var m` works just fine (and fixes all following `expr m` calls).
The reason for why `expr` breaks std::map is that we actually copy the std::map nodes in two steps in the
three ASTContexts that are involved: The debug information ASTContext (D-AST), the expression ASTContext
we created for the current expression (E-AST) and the persistent ASTContext we use for our $variables (P-AST).
When doing `expr m` we do a minimal import of `std::map` from D-AST to E-AST just do the type checking/codegen.
This copies std::map itself and does a minimal.import of `std::pair<int, int>` (that is, we don't actually import
the `first` and `second` members as we don't need them for anything). After the expression is done, we take
the expression result and copy it from E-AST to P-AST. This imports the E-AST's `std::pair` into P-AST which still
has no `first` and `second` as they are still undeserialized. Once we are in P-AST, the data formatter tries to
inspect `std::map` (and also `std::pair` as that's what the elements are) and it asks for the `std::pair` members.
We see that `std::pair` has undeserialized members and go to the ExternalASTSource to ask for them. However,
P-ASTs ExternalASTSource points to D-AST (and not E-AST, which `std::pair` came from). It can't point to E-AST
as that is only temporary and already gone (and also doesn't actually contain all decls we have in P-AST).
So we go to D-AST to get the `std::pair` members. The ASTImporter is asked to copy over `std::pair` members
and first checks if `std::pair` is already in P-AST. However, it only finds the std::pair we got from E-AST, so it
can't use it's map of already imported declarations and does a comparison between the `std::pair` decls we have
Because the ASTImporter thinks they are different declarations, it creates a second `std::pair` and fills in the
members `first` and `second` into the second `std::pair`. However, the data formatter is looking at the first
`std::pair` which still has no members as they are in the other decl. Now we pretend we have no declarations
and just print an empty map as a fallback.
The hack we had before fixed this issue by moving `first` and `second` to the first declaration which makes
the formatters happy as they can now see the members in the DeclContext they are querying.
Obviously this is a temporary patch until we get a real fix but I'm not sure what's the best way to fix this.
Implementing that the ClassTemplateSpecializationDecl actually understands that the two std::pair's are the same
decl fixes the issue, but this doesn't fix the bug for all declarations. My preferred solution would be to
complete all declarations in E-AST before they get moved to P-AST (as we anyway have to do this from what I can
tell), but that might have unintended side-effects and not sure what's the best way to implement this.

v2i32 isn't a legal type. The bitcast+build_vector would be DAG

[X86] X86DAGToDAGISel::matchBEXTRFromAndImm(): if can't use BEXTR, fallback to BZHI is profitable (PR43381)
Summary:
PR43381 notes that while we are good at matching `(X >> C1) & C2` as BEXTR/BEXTRI,
we only do that if we either have BEXTRI (TBM),
or if BEXTR is marked as being fast (`-mattr=+fast-bextr`).
In all other cases we don't match.
But that is mainly only true for AMD CPU's.
However, for all the CPU's for which we have sched models,
the BZHI is always fast (or the sched models are all bad.)
So if we decide that it's unprofitable to emit BEXTR/BEXTRI,
we should consider falling-back to BZHI if it is available,
and follow-up with the shift.
While it's really tempting to do something because it's cool
it is wise to first think whether it actually makes sense to do.
We shouldn't just use BZHI because we can, but only it it is beneficial.
In particular, it isn't really worth it if the input is a register,
mask is small, or we can fold a load.
But it is worth it if the mask does not fit into 32-bits.
(careful, i don't know much about intel cpu's, my choice of `-mcpu` may be bad here)
Thus we manage to fold a load:
https://godbolt.org/z/Er0OQz
Or if we'd end up using BZHI anyways because the mask is large:
https://godbolt.org/z/dBJ_5h
But this isn'r actually profitable in general case,
e.g. here we'd increase microop count
(the register renaming is free, mca does not model that there it seems)
https://godbolt.org/z/k6wFoz
Likewise, not worth it if we just get load folding:
