Debugger autodetection uses clang regex for gcc

[veimmone]

I don't have any experience in developing VS Code extensions so I don't even try to make a proper patch, but I found out that here:

vscode-cmake-tools/src/debugger.ts

Line 219 in 406216a

miDebuggerPath = compilerPath.replace(clangCompilerRegex, 'gdb');

the compilerPath.replace operation is using a clang-specific regex. In my local dist/main.js I replaced this line with:

miDebuggerPath = compilerPath.replace('gcc', 'gdb').replace('g++', 'gdb');

and got further on my bughunt. You might want to think if a similar regex as for clang.

(As a sidenote, it seems that when using a toolchain file with CMake, the CMAKE_<lang>_COMPILER variables don't necessarily end up in CMakeCache.txt so this method of auto-detection based on the cache fails to begin with...)
