testhost.x86.exe should be able to handle large addresses.

[harshjain2]

Description

There could be scenarios where testhost.x86.exe requires more than 2 GB of memory. In those cases, current testhost.x86.exe could fail with StackOverFlowException/OutOfMemoryException as 32-bit programs receive only 2 GB of address space.

We should consider using /LARGEADDRESSAWARE flag in testhost.x86.exe.
When this flag is used while compiling, testhost.x86.exe can use up to 4GB of address space.

We also need to investigate the same has to be applied in DataCollector.exe and vstest.console.exe as well.

Current Status:

Currently dotnet tooling doesn't have support to use /LARGEADDRESSAWARE for cross plat. See related issue in compiler.

Workaround:

User can run their test for platform x64.

Action:

Moving this bug from milestone 15.5 and will address once the above issue will get fixed.

@Faizan2304 The required compiler feature is already implemented going back to the first VS2015 release. It's just really sneaky. See my comment in the linked issue. 😄

this appears to have been fixed in VS 2019

Weird. I refiled this as #1985 and then fixed it in #1986.

Weird because I commented in this issue, so I have no excuse for not knowing about its existence earlier. 😆

@sharwell Cool! Thanks.
@fifthgearonline Thanks for confirmation.
