Fixes https://github.com/dlang/dmd/issues/20423
Ultimate cause of this issue was that va_arg was being shadowed
by the collected template-like macros. As va_arg is not a normal
function (it takes a type as a parameter), this interfered with
the cparser's rewrite of va_arg to a call to the single argument
template version in core.stdc.stdarg.

After preprocessing, #defines in C code that are just string literals
are converted into D enums. As these are collected for use in D code,
they should behave like D string literals and not C string literals.
Resolves https://github.com/dlang/dmd/issues/20434
Allowing this gnu/clang extension actually removes lines of code as
we can unify the parsing and semantics of `_Alignof` and `sizeof`
and have the normal D machinery handle the difference later.
Fixes https://github.com/dlang/dmd/issues/20472
Arrays in C implicitly convert to a pointer to their first member,
so do the implicit conversion when using them in an arrow member lookup.
The gnu attribute aligned() allows specifying the alignment of an entire
struct, mostly as a syntatic convenience. This attribute allows
compile-time integer expressions, but the parser was trying to evaluate them
ahead of time by checking for an integer literal. Instead we need to
preserve the expression and defer it to a later semantic stage.
Accomplish this by emulating the behavior by specifying the alignment of
the first member of the struct.
I didn't change how __declspec(align(#)) parses as from the
documentation it seems to only allow integer literals. Some light
testing with cl.exe gives syntax errors when trying to use _Alignof() in
that position.
* bump VERSION to v2.110.0
* purge changelog
* bump VERSION to v2.111.0-beta.1
* Accept __rvalue attribute on ref functions; which will force the result to be treated as __rvalue. (#20946)
This is essential to implement `move`, `forward`, etc.
* memoryerror.d: Fix AnySupported version condition (#20983)
* Fix#20982 - wrong line number in iasmgcc (#20993)
* Move genCfunc to cxxfrontend (#20992)
* druntime: Fix compilation of rt.cover on Android (#21015)
* Expose SourceLoc to C++ interface (#20980)
* [stable] C++ header fixes for declaration, expression, and typinf (#21016)
Seen either from compilation errors or missing symbols at link time.
* C++ headers: Add 3 Declaration bitfield setters/getters required by LDC
* druntime: Add module declaration to rt.invariant, to prevent conflicts with user-provided invariant.d (#21017)
* Fix#21020 - Indexing a *cast* AA yields no lvalue anymore (#21029)
* Add C++23 to CppStdRevision enum (#21043)
* Improve UFCS/property error message (#21046)
* bump VERSION to v2.111.0-rc.1
* Fix#21045 - import __stdin causes compilation to pause while reading from stdin (#21047)
Moves the special handling of reading from stdin out of the semantic
routines to the DMD driver itself. All references to `__stdin.d` have
also been removed from the frontend implementation.
* Update source code and coverage links (#21111)
* Fix#21024 - Optimize x^^c expressions (#21082)
* Fix#21024 - Optimize x^^c expressions
Reason for the *magic* constraint c<8 on inlining x^^c:
https://sourceware.org/git/?p=glibc.git;a=blob;f=sysdeps/x86_64/fpu/e_powl.S;h=47f129f34d368d7c67b8e5f2462b36b0bebb7621;hb=HEAD#l136
* Fix poor assumption about expression state
* Restrict optimization to floating point expressions
* Generalize optimization to any scalar data type
* Fix segfault on x^^c where x is a single member anonymous enum
DMD segfaulted on compiling the unittests in std/algorithm/sorting.o, the
unittest that caused the segfault can be reduced to:
enum real Two = 2.0;
auto _ = Two^^3;
I'm not sure why copying the anonymous enum into a `const` variable causes
the compiler to segfault.
* Add tests to x^^c inlining optimization
* Fix missing type for e1 ^^ -1 to 1 / e1 rewrite
* Move rewrites from constant folding to expression semantic and restrict them to [-1, 2]
* Improve error message for the x^^2 rewrite.
Before:
ex.d(4): Error: can implicitly convert expression `(const const(double) __powtmp2 = x + 5.0;) , __powtmp2 * ...` of type `double` to `int`
int y = ( x + 5 ) ^^ 2;
^
and after:
ex.d(4): Error: cannot implicitly convert expression `(x + 5.0) ^^ 2L` of type `double` to `int`
int y = ( x + 5 ) ^^ 2;
^
* Update C++ frontend header to match change in `CommaExp`
* Address code review feedback
