e1ea21fd5d Some cleanup and bulletproofing for node replacement in LegalizeDAG. To maintain LegalizeDAG invariants, whenever we a node is replaced, we must attempt to delete it, and if it still 
has uses after it is replaced (which can happen in rare cases due to CSE), we must revisit it.

bc077320e1 ARM vldm and vstm VFP instructions can take a data type suffix. 
It's ignored by the assembler when present, but is legal syntax. Other
instructions have something similar, but for some mnemonics it's
only sometimes not significant, so this quick check in the parser will
need refactored into something more robust soon-ish. This gets some
basics working in the meantime.

bc4e9ca90e Mips MC object code emission improvements: 
"With this patch we can now generate runnable Mips code through LLVM
direct object emission. We have run numerous simple programs, both C
and C++ and with -O0 and -O3 from the output. The code is not production
ready, but quite useful for experimentation." Patch and message by
Jack Carter

a52be4ff03 Clients are responsible for initializing the targets, remove it from the disassembler API. 
This will break users of the LLVMCreateDisasm API (not that I know of any). They have to call the 
LLVMInitializeAll* functions from llvm-c/Target.h themselves now. edis' C API in all its horribleness 
should be unaffected.

127d98ab35 Get rid of an optimization in SCCP which appears to have many issues. Specifically, it doesn't handle many cases involving undef correctly, and it is missing other checks which 
lead to it trying to re-mark a value marked as a constant with a different value.  It also appears to trigger very rarely.

Fixes PR11357.
