9d534790eb std.Target: Introduce Cpu convenience functions for feature tests. 
Before:

* std.Target.arm.featureSetHas(target.cpu.features, .has_v7)
* std.Target.x86.featureSetHasAny(target.cpu.features, .{ .sse, .avx, .cmov })
* std.Target.wasm.featureSetHasAll(target.cpu.features, .{ .atomics, .bulk_memory })

After:

* target.cpu.has(.arm, .has_v7)
* target.cpu.hasAny(.x86, &.{ .sse, .avx, .cmov })
* target.cpu.hasAll(.wasm, &.{ .atomics, .bulk_memory })

compiler-rt, zigc: Use hidden visibility except when testing. 
This prevents symbols from these libraries from polluting the dynamic symbol
tables of binaries built with Zig. The downside is that we no longer deduplicate
the symbols at run time due to weak linkage.

Closes #7935.
Closes #13303.
Closes #19342.

std.Target: Remove functions that just wrap component functions. 
Functions like isMinGW() and isGnuLibC() have a good reason to exist: They look
at multiple components of the target. But functions like isWasm(), isDarwin(),
isGnu(), etc only exist to save 4-8 characters. I don't think this is a good
enough reason to keep them, especially given that:

* It's not immediately obvious to a reader whether target.isDarwin() means the
  same thing as target.os.tag.isDarwin() precisely because isMinGW() and similar
  functions *do* look at multiple components.
* It's not clear where we would draw the line. The logical conclusion before
  this commit would be to also wrap Arch.isX86(), Os.Tag.isSolarish(),
  Abi.isOpenHarmony(), etc... this obviously quickly gets out of hand.
* It's nice to just have a single correct way of doing something.

6dc1a4db7f compiler-rt: fix memcpy generating recursive calls 
When using the LLVM backend, array copies were lowered as calls to
`llvm.memcpy.*` builtin which could cause recursive calls to memcpy to
be generated (observed with `-target x86_64-linux -mcpu x86_64+avx512vl
--debug-rt`).

By instead performing these small fixed-size copies with integers or
vectors the LLVM backend does not generate calls to the `llvm.memcpy`
builtin, and so (with `-fno-builtin`) recursive calls to memcpy will
not be generated by LLVM.

The assertions and (test build) runtime safety have been removed as they
may cause (mutually) recursive calls to memcpy in debug builds since the
panic handler generates calls to llvm.memcpy.

b7a887f0fb compiler-rt: optimize memcpy 
The new memcpy function aims to be more generic than the previous
implementation which was adapted from an implementation optimized for
x86_64 avx2 machines. Even on x86_64 avx2 machines this implementation
should be generally be faster due to fewer branches in the small length
cases and generating less machine code.

Note that the new memcpy function no longer acts as a memmove.
