The next chunk of Shreya's work.
For this expansion we want to detect cases when the mask fits in a
simm12 after shifting right by the number of trailing zeros in the mask.
In that case we can synthesize the AND with a shift right, andi and
shift left. I saw this case come up when doing some

So this patch from Shreya adds the ability to use andi + a series of
bclr insns to synthesize a logical AND, much like we're doing for
IOR/XOR using ori+bset or their xor equivalents.
This would regress from a code quality standpoint if we didn't make some
adjustments to a handful of define_in

You're right, th
The array that stores the dynamic extents used to be default
initialized. The standard requires value intialization. This
commit fixes the bug and adds a test.

* include/std/mdspan: Value initialize the array storing the
dynamic extents.
* testsuite
This is in preparation for the installation of the ACATS 4.2 testsuite.
Tested on x86-64/Linux, applied on the mainline.
