[asan] Intercept RtlRaiseException instead of kernel32!RaiseException
Summary:
On my install of Windows 10, RaiseException is a tail call to
kernelbase!RaiseException. Obviously, we fail to intercept that.
Instead, try hooking at the ntdll!RtlRaiseException layer. It is
unlikely that this layer will contain control flow.
Intercepting at this level requires adding a decoding for
'LEA ESP, [ESP + 0xXXXXXXXX]', which is a really obscure way to write
'SUB ESP, 0xXXXXXXXX' that avoids clobbering EFLAGS.
