[Lldb-commits] [PATCH] D41584: Check existence of each required component during construction of LLVMCDisassembler.

[Tatyana Krasnukha via Phabricator via lldb-commits]

Actually, fix two issues:

1. remove repeat creation of reg_info, use m_reg_info_ap  for createMCAsmInfo instead;
2. remove possibility to dereference nullptr during createMCAsmInfo invocation, that could lead to undefined behavior.

Placed checking of a component right after its creation to simplify the code and avoid same issues later.
