ecs; ide/Project: (#1063) Fixed Windows build issues with ecs overflowing command-line
compiler/libec: Added support for symbolic identifier for GCC inline assembly
- Missing support was breaking the builds with MinGW-w64 GCC 4.8
compiler/libec: Ignoring warnings coming from intrin-impl.h with MinGW-w64 GCC 4.8
- A bunch of built-in GCC functions with no declarations causes these warnings (a glance at the generated code looked all good)
