The mul64 attribute in types.md causes some confusion as it is used to represent
aarch32 instructions that do widening multiplication to generate 32->64 bit results.
But these types are shared with aarch64, which has native 64-bit multiplication operations.
Those are currently not properly represented, which I will fix in follow-up patches.
For now, this patch renames the mul64 attribute to widen_mul64 to more clearly communicate its meaning.
It mechanically updates all users of that name in config/arm/ (there are no users in config/aarch64).
There is thus no change in behaviour.

When throwing an Exception in the Fiber the backtrace generation
crashes. This happens because backtrace does not func the stack bottom.
Using '.cfi_undefined x30' tells the debug info that the value in the lr
is unknown, which seems to be the nicest way to stop the unwinder.
Setting x30 to 0 is another option, however it still creates one invalid
frame in gdb, so the .cfi variant is used here instead.
Backport from upstream druntime 2.083.

With multiple threads, using an unprotected static variable to check
whether recursion has occured isn't valid, as one thread might have
modified the variable, thus causing another thread to incorrectly
conclude that recursion has occured. This patch avoids this problem
by using a thread-specific variable for the recursion check.
Regtested on x86_64-pc-linux-gnu.

The pretty printer for std::any fails when the contained value is a
locally-defined type, because the name in the debuginfo has
cv-qualifiers and ptr-declarators in different positions. The unexpected
format confuses the printer. This makes the printer's regex handle
either format.
This isn't a complete fix because looking up the contained type fails
when there are two types with the same name (defined in different local
scopes). This applies to all closure types defined in a given function,
as they all appear as "func()::lambda" in the debuginfo names.
