From 72f310a6c3dccbabf9edc29677b51ed78c87cc67 Mon Sep 17 00:00:00 2001

Subject: [PATCH 1/3] [wasm] Endian fix for Webcil
'dotnet new blazorwasm' command failed on s390x and was throwing a not implemented exception
The issue was with with the WebCil writer and reader, specific endianness conversions relating to the webcil payload were not implemented for big endian machines.
We considered fixing the generic implementation, but there were only two structures in use: WebcilHeader and WebcilSectionHeader, so it was easier to handle them explicitly.
