ea9951d3a9 MSVC: Fix warnings c4244 and c4267 in the main library code 
These are integer-type shortening warnings.
These warnings are still disabled in tests.

c4244: conversion from 'type1' to 'type2', possible loss of data

c4267: conversion from 'size_t' to 'type', possible loss of data
https://learn.microsoft.com/en-us/cpp/error-messages/compiler-warnings/compiler-warning-level-3-c4267?view=msvc-170

78ed38cf2c PR #1783: [riscv][debugging] Fix a few warnings in RISC-V inlines 
Imported from GitHub PR https://github.com/abseil/abseil-cpp/pull/1783

Today we cannot build V8 (which uses the Abseil library) in strict mode for RISC-V due to a few warnings in debbugging inlines. All the warnings are about implicit signed to unsigned conversion and precision losses, nothing serious, but they are still very annoying.

1278ee9bd9 vdso_support: support DT_GNU_HASH 
This library provides `LookupSymbol` and `LookupSymbolByAddress`. The latter
needs `GetNumSymbols` support. An object file needs either .hash (DT_HASH) or
.gnu.hash (DT_GNU_HASH). This patch adds DT_GNU_HASH support.

Note: glibc has been supporting DT_GNU_HASH since 2006 and .hash has been quite
obsoleted in the Linux communities.
