Nicolas GonzalezandClaude Opus 5.5 b6c87fa45f perf(shader): check only the carry on scalar buffer reads bound to their exact range ...

A scalar buffer read through a static V# checks the carry, that the V# is
present and the offset against the V# size in 64 bits, and then the
offset against the binding's length. When the V# base is DWORD aligned,
the binding starts at the base and spans the V# size (less where it is
cut), and a V# that is not present is bound to the empty placeholder, so
the length check alone gives the same value once that placeholder reads
as zero. Zero the placeholder when it is created and keep only the carry
check there. A base off a DWORD boundary keeps every check, since its
view is rounded up a DWORD. Devices with exact robust loads have no
length check and are unchanged.
