  [lldb][NFC] Simplify logic in ABIMacOSX_arm64::FixDataAddress (#159612)

I've intentionally split this into two commits to make it easier that
this is an NFC patch; don't think we need to preserve them separately
though upon merging.

  [libc][bazel] Add Bazel rules for rand/srand functions. (#159617)

These functions are unlikely to be used in the overlay mode (since they are stateful), but it's worth verifying the correctness of underlying RNG (which may be reused in other places) in Bazel build regardless.

  [SFrames] reland Emit and relax FREs #158154 (#159643)

[Previously reverted due to msan failures on two uninitialized padding
bits.]

This PR emits and relaxes the FREs generated in the previous PR.

After this change llvm emits usable sframe sections that can be linked
with the gnu linker. There are a few remaining cfi directives to handle
before they are generally usable, however.

The output isn't identical with gnu-gas in every case (this code
produces fewer identical FREs in a row than gas), but I'm reasonably
sure that they are correct regardless. There are even more size
optimizations that can be done later.

Also, while working on the tests, I found a few bugs in older portions
and cleaned those up.

This is a fairly big commit, but I'm not sure how to make it smaller.

  [mlir][spirv] Use `verifySymbolUses` for `spirv.FunctionCall`. (#159399)

`spirv.FunctionCall`'s verifier was being too aggressive. It included
verification of non-local properties by looking at the callee's
definition.

This caused problems in cases where callee had verification errors and
could lead to null pointer dereferencing.

According to [MLIR's developers guide
](https://mlir.llvm.org/getting_started/DeveloperGuide/#ir-verifier)

> TLDR: only verify local aspects of an operation,
> in particular don’t follow def-use chains
> (don’t look at the producer of any operand or the user
>  of any results).

The fix includes adding the `SymbolUserOpInterface` to `FunctionCall`
and moving most of the verification logic to `verifySymbolUses`.

Fixes #159295

  [HLSL] Make sure global resources and resource arrays cannot be assigned to (#157772)

Global resources are read-only. The compiler needs to report an error when somebody attempts to assign a value to a global resource, a global resource array element or the whole array.

Test update in `static-local-ctor.hlsl` includes the use of the llvm-cxxfilt tool which takes care of demangling of function names for a more readable test baseline.

Closes #154390

This is needed because, `vector-to-llvm` does not linearize all the

  [PowerPC] fix float ABI selection on ppcle (#154773)

soft float ABI selection was not taking effect on little-endian powerPC
with embedded vectors (e.g. e500v2) leading to errors.
(embedded vectors use "extended" GPRs to store floating-point values,
and this caused issues with variadic arguments assuming dedicated
floating-point registers with hard-float ABI)
