ARM64: Fix Small Operation For optOptimizeBools

Fixes https://github.com/dotnet/coreclr/issues/5955

When merging two boolean operations (cmp/jmp) in optOptimizeBools, JIT
creates type based on operand type.
There is a case the operand type is bool (1 byte) so JIT creates a tree
that does 1 byte operation which arm64 cannot encode.
The fix is to bail out such case for arm in general.

This passes all 1375 tests in System.Net.Http.Unit.Tests.
