Release v6.3

Summary:
This release adds preliminary support to track the stack size during the execution of the C programs. In particular, this property checks whether, for a given program, an execution path exceeds a maximum limit for the stack.

New features:

• Stack property verification.
• ESBMC now supports Microsoft extensions.
• -f an -W flags are forwarded into clang.
• Float models refactoring, which enabled macOS CI.

Fixes:

• Fixed issue that caused a dereference violation in VLAs.
• Union bitfields no longer throw a segfault.
• Unary side effects are appropriately handled.
• CVC4 encoding for FPs is fixed.
