Nikita Popov b75c8fc6fb [X86] Fix stack probing on x32 (PR41477)
Fix for https://bugs.llvm.org/show_bug.cgi?id=41477. On the x32 ABI
with stack probing a dynamic alloca will result in a WIN_ALLOCA_32
with a 32-bit size. The current implementation tries to copy it into
RAX, resulting in a physreg copy error. Fix this by copying to EAX
instead. Also fix incorrect opcodes or registers used in subs.

Craig Topper 4d4b5d952e [X86] Don't turn (and (shl X, C1), C2) into (shl (and X, (C1 >> C2), C2) if the original AND can represented by MOVZX.
The MOVZX doesn't require an immediate to be encoded at all. Though it does use
a 2 byte opcode so its the same size as a 1 byte immediate. But it has a
separate source and dest register so can help avoid copies.

Craig Topper 8b8264828c [X86] Turn (and (anyextend (shl X, C1), C2)) into (shl (and (anyextend X), (C1 >> C2), C2) if the AND could match a movzx.
There's one slight regression in here because we don't check that the immediate
already allowed movzx before the shift. I'll fix that next.

Thomas Lively 84771e2d21 [WebAssembly] Emit the DataCount section when bulk memory is enabled
Summary:
The DataCount section is necessary for the bulk memory operations
memory.init and data.drop to validate, but it is not recognized by
engines that do not support bulk memory, so emit the section only if
bulk-memory is enabled.

David Blaikie 07489f9ccf Modules: Adopt template parameters for variable templates to set their decl context correctly
Exposed by a related bug about visibility of default arguments of nested
templates - without the correct decl context, default template
parameters of variable templates nested in classes would have incorrect
visibility computed.

David Blaikie aa3bf6ce72 Modules: Search for a visible definition of the decl context when computing visibility of a default template parameter
The code is/was already correct for the case where a parameter is a
parameter of its enclosing lexical DeclContext (functions and classes).
But for other templates (alias and variable templates) they don't create
their own scope to be members of - in those cases, they parameter should
be considered visible if any definition of the lexical decl context is
visible.

[this should cleanup the failure on the libstdc++ modules buildbot]
[this doesn't actually fix the variable template case for a
secondary/compounding reason (its lexical decl context is incorrectly
considered to be the translation unit)]

Test covers all 4 kinds of templates with default args, including a
regression test for the still broken variable template case.

Reid Kleckner a30920c31f [COFF] Pack Name in Symbol as is done in ELF
Summary:
This assumes all symbols are <4GB long, so we can store them as a 32-bit
integer. This reorders the fields so the length appears first, packing
with the other bitfield data in the base Symbol object.

This saved 70MB / 3.60% of heap allocations when linking
browser_tests.exe with no PDB. It's not much as a percentage, but worth
doing. I didn't do performance measurements, I don't think it will be
measurable in time.

Sam Clegg a27252794e [WebAssembly] FastISel: Don't fallback to SelectionDAG after BuildMI in selectCall
My understanding is that once BuildMI has been called we can't fallback
to SelectionDAG.

This change moves the fallback for when getRegForValue() fails for
that target of an indirect call.  This was failing in -fPIC mode when
the callee is GlobalValue.

Add a test case that tickles this.

This is a follow-up to r291037+r291258, which used null debug locations
to prevent jumpy line tables.

Using line 0 locations achieves the same effect, but works better for
crash attribution because it preserves the right inline scope.

Martin Storsjo 93f7d83b36 [MSVC] If unable to find link.exe from a MSVC installation, look for link.exe next to cl.exe
Previously, if the MSVC installation isn't detected properly, clang
will later just fail to execute link.exe.

This improves using clang in msvc mode on linux, where one intentionally
might not want to point clang to the MSVC installation itself (which
isn't executable as such), but where a link.exe named wine wrapper is
available in the path next to a cl.exe named wine wrapper.
