Subject: [PATCH] PR #1929: Fix shorten-64-to-32 warning in
 stacktrace_riscv-inl.inc

Imported from GitHub PR https://github.com/abseil/abseil-cpp/pull/1929

`ComputeStackFrameSize` returns `ptrdiff_t` which is `long` while `sizes[n]` is `int`.

This would become an error in chromium build as chromium enables warnings_as_error by default.

Merge ad1d6805b5088a24c5d8126bd45e2212113afd8e into f040e96b93dba46e8ed3ca59c0444cbd6c0a0955

Merging this change closes #1929
