When ASan testing is enabled on SPARC as per PR #107405, the
```
AddressSanitizer-sparc-linux :: TestCases/Linux/ptrace.cpp
```
`FAIL`s on Linux/sparc64. This happens because the `ptrace` interceptor
has no support for that target at all.
This patch adds the missing parts and accounts for a couple of issues
specific to this target:
- In some cases, SPARC just needs to be included in the list of
supported targets.
- Besides, the types used by the `PTRACE_GETREGS` and `PTRACE_GETFPREGS`
requests need to be filled in.
- `ptrace` has a weird quirk on this target: for a couple of requests,
the meaning of the `data` and `addr` args is reversed. All of the
`Linux/ptrace.cpp` test and the interceptor, pre-syscall and
post-syscall hooks need to account for that swap in their checks.
Tested on `sparc64-unknown-linux-gnu` and `x86_64-pc-linux-gnu`.
Add ptrace interceptor support for LoongArch, `ptrace.cpp` has been
tested and passed.

[11/11] patch series to port ASAN for riscv64
These changes allow using ASAN on RISCV64 architecture.
The majority of existing tests are passing. With few exceptions (see below).
Tests we run on qemu and on "HiFive Unleashed" board.
Tests run:
```
Asan-riscv64-inline-Test - pass
Asan-riscv64-inline-Noinst-Test - pass
Asan-riscv64-calls-Noinst-Test - pass
Asan-riscv64-calls-Test - pass
```
Lit tests:
```
RISCV64LinuxConfig (282 supported, few failures)
RISCV64LinuxDynamicConfig (289 supported, few failures)
```
Lit failures:
```
TestCases/malloc_context_size.cpp - asan works, but backtrace misses some calls
TestCases/Linux/malloc_delete_mismatch.cpp - asan works, but backtrace misses some calls
TestCases/Linux/static_tls.cpp - "Can't guess glibc version" (under debugging)
TestCases/asan_and_llvm_coverage_test.cpp - missing libclang_rt.profile-riscv64.a
```
These failures are under debugging currently and shall be addressed in a
subsequent commits.
Depends On D87581
