cpptools.exe is a 32-bit process

[Rattenhirn]

Bug type: Language Service (I think)

Describe the bug

• OS and Version: Windows 10.0.19042 Build 19042
• VS Code Version: 1.61.2
• C/C++ Extension Version: v1.7.1

When installing the extension through VS Code Extensions or using the .vsix from GitHub, it will still always launch the 32-bit version of cpptools.exe. When working with a large project, over time this can hit the 2 GiB memory limits that 32-bit processes have, slowing down everything, despite enough memory being available on the system.

Steps to reproduce

1. Install C/C++ extension
2. Open a project with C/C++ files in it
3. Observe the bit-ness of the cpptools.exe process in Process Explorer

Expected behavior
A 64-bit version of cpptools.exe being launched

We will release a 64-bit cpptools.exe as part of #8152 which should be in the next release (1.8.0).

Fixed with https://github.com/microsoft/vscode-cpptools/releases/tag/1.8.0-insiders3 or 1.8.0 (via using VS Code's "Pre-Release Version" UI or https://marketplace.visualstudio.com/items?itemName=ms-vscode.cpptools&ssr=false#version-history ).
