Regression between 0.8.29 and 0.8.30 with GCC 14.2.1 on AArch64 and PPC64le

## Description

Solidity build fails with GCC 14.2.1 on AArch64 and PPC64le but completes just fine on these arches with a more modern GCC 15.1.1. On X86_64 it compiles just fine with both GCC versions.

## Environment

- Compiler version: GCC 14.2.1
- Compilation pipeline (legacy, IR, EOF): n/a
- Target EVM version (as per compiler settings): n/a
- Framework/IDE (e.g. Foundry, Hardhat, Remix): n/a
- EVM execution environment / backend / blockchain client: n/a
- Operating system: Linux

## Steps to Reproduce

I've tried to build solidity with the following parameters (note the `-Werror=array-bounds` parameter implied by `-Wall`):

```sh
CFLAGS='-O2 -flto=auto -ffat-lto-objects -fexceptions -g -grecord-gcc-switches -pipe -Wall -Werror=format-security -Wp,-U_FORTIFY_SOURCE,-D_FORTIFY_SOURCE=3 -Wp,-D_GLIBCXX_ASSERTIONS -specs=/usr/lib/rpm/redhat/redhat-hardened-cc1 -fstack-protector-strong -specs=/usr/lib/rpm/redhat/redhat-annobin-cc1 -m64 -mcpu=power8 -mtune=power8 -fasynchronous-unwind-tables -fstack-clash-protection '
CXXFLAGS='-O2 -flto=auto -ffat-lto-objects -fexceptions -g -grecord-gcc-switches -pipe -Wall -Werror=format-security -Wp,-U_FORTIFY_SOURCE,-D_FORTIFY_SOURCE=3 -Wp,-D_GLIBCXX_ASSERTIONS -specs=/usr/lib/rpm/redhat/redhat-hardened-cc1 -fstack-protector-strong -specs=/usr/lib/rpm/redhat/redhat-annobin-cc1 -m64 -mcpu=power8 -mtune=power8 -fasynchronous-unwind-tables -fstack-clash-protection '
...
/usr/bin/cmake -S . -B redhat-linux-build -DCMAKE_C_FLAGS_RELEASE:STRING=-DNDEBUG -DCMAKE_CXX_FLAGS_RELEASE:STRING=-DNDEBUG -DCMAKE_Fortran_FLAGS_RELEASE:STRING=-DNDEBUG -DCMAKE_VERBOSE_MAKEFILE:BOOL=ON -DCMAKE_INSTALL_DO_STRIP:BOOL=OFF -DCMAKE_INSTALL_PREFIX:PATH=/usr -DCMAKE_INSTALL_FULL_SBINDIR:PATH=/usr/sbin -DCMAKE_INSTALL_SBINDIR:PATH=sbin -DINCLUDE_INSTALL_DIR:PATH=/usr/include -DLIB_INSTALL_DIR:PATH=/usr/lib64 -DSYSCONF_INSTALL_DIR:PATH=/etc -DSHARE_INSTALL_PREFIX:PATH=/usr/share -DLIB_SUFFIX=64 -DBUILD_SHARED_LIBS:BOOL=ON -DIGNORE_VENDORED_DEPENDENCIES:BOOL=ON -DBoost_USE_STATIC_LIBS:BOOL=OFF -DSTRICT_Z3_VERSION:BOOL=OFF -DTESTS:BOOL=OFF
```
It works just fine on x86_64 with this old GCC version but fails on secondary arches (aarch64, ppc64le) with the following stacktrace:

I suspect this is likely a compiler's bug but maybe we could hint it somehow to calculate arrays properly?

Again everything is totally fine on x86_64, that's just a problem with non-Intel/AMD arches with a non-recent compiler.

Start with libsolidity/analysis/ControlFlowRevertPruner.cpp around lines 132 and 148, where GCC 14.2.1 reports the array-bounds error, and compare the 0.8.29 and 0.8.30 implementations. Reproduce the provided CMake build on AArch64 or PPC64le with GCC 14.2.1 and confirm that the build completes with the shown warning flags while preserving the successful GCC 15.1.1 and x86_64 builds.
