N32/64 places all variable arguments in integer registers (or on stack),
regardless of their types, but follows calling convention of non-vaarg function
when it handles fixed arguments.

argument registers on the callee's stack frame, along with functions that set
and get it.
    
It is not necessary to add the size of this area when computing stack size in
emitPrologue, since it has already been accounted for in
PEI::calculateFrameObjectOffsets.

build: Attempt to rectify inconsistencies between CMake and LLVMBuild versions of explicit dependencies.
 - The hope is that we have a tool/test to verify these are accurate (and tight) soon.

"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

handle defining the "magic" target related components (like native,
nativecodegen, and engine).
 - We still require these components to be in the project (currently in
   lib/Target) so that we have a place to document them and hopefully make it
   more obvious that they are "magic".

 - Gives us a place to hang target specific metadata (like whether the target has a JIT).

When this field is true it means that the load is from constant (runt-time or compile-time) and so can be hoisted from loops or moved around other memory accesses

implements unaligned loads and stores with assembler macro-instructions
ulw, usw, ulh, ulhu, ush, and this patch emits corresponding instructions
instead of these macros. Since each unaligned load/store is expanded
into two corresponding loads/stores where offset for second load/store is
modified by +3 (for words) or +1 (for halfwords).
