If we can't determine what variable is accessed, we should assume it could
be any.
This might make things worse with Vulkan since it does
vulkan_resource_index+load_vulkan_descriptor, but I don't think it matters
much. SSBO stores are rarely used in vertex shaders.

The nil Rust test fails to link when built under Coverity (cov-build):
/usr/bin/ld: src/util/libmesa_util.a.p/format_u_format_other.c.o:
undefined reference to symbol 'sqrtf@@GLIBC_2.2.5'
/usr/bin/ld: /lib/x86_64-linux-gnu/libm.so.6:
error adding symbols: DSO missing from command line
This does not reproduce with plain GCC or Clang builds.
When rustc invokes the linker for the nil test binary, the generated
link command is structured as:
cc ... [Rust rlibs] -Bdynamic -lm -ldl -lc ...
-fuse-ld=lld -B.../gcc-ld ...
[static archives: libmesa_util.a ...]
The -lm appears before libmesa_util.a in both Coverity and non-Coverity
builds. With --as-needed enabled, the linker only records a shared
library as needed if it resolves an undefined symbol at the point it
is encountered. Since no symbols need -lm when it is first seen, the
outcome depends on the linker implementation:
- lld (rustc's bundled linker, used in plain builds): Tolerates
back-references from later static archives to earlier shared
libraries, so libmesa_util.a's sqrtf reference is still resolved
by the previously-seen libm.so.
- ld.bfd (GNU ld): Strict single-pass left-to-right. Once -lm is
skipped by --as-needed, it cannot satisfy sqrtf when libmesa_util.a
is processed later.
Coverity's cov-build wrapper intercepts rustc's call to the linker
and strips the -fuse-ld=lld and -B.../gcc-ld arguments, causing the
linker to fall back to the system's ld.bfd. This exposes the latent
link-order problem that lld was masking.
The underlying issue is that rustc places default libraries (-lm, -lc,
etc.) before user-specified static archives in the link command, which
is a known rustc limitation.
See also: https://github.com/rust-lang/rust/issues/154975
Fix this by passing -lm via rust_args with --no-as-needed brackets.
This forces ld.bfd to record libm as needed regardless of when it
appears on the command line, so sqrtf from libmesa_util.a is resolved
correctly under both lld and ld.bfd.

It is sometimes useful to remove all elements of a bitset while retaining the
backing storage. With a dense bitset, we would just memset everything to 0,
which is O(capacity). With a sparse bitset, previously we would have to free and
reallocate, which is O(capacity) in the dense case and O(cardinality) in the
sparse case. That is the correct asymptoptic behaviour O(cardinality) in the
worst case, but there is an unfortunate constant-factor associated with the
redundant allocation & free in the dense case.
Therefore, we add a new helper to clear all elements of the sparse bitset in one
go, avoiding reallocation in the dense case.
