46c3ebc1a6 Implement a correct copy constructor for Record. Now that we're using the ID number as a key in maps (for determinism), it is imperative that ID numbers be globally unique, even when we copy construct a Record. 
This fixes some obscure failure cases involving registers defined inside multiclasses or foreach constructs that would not receive a unique ID, and would end up being omitted from the AsmMatcher tables.

79d6f55f89 Add support for macro parameters/arguments delimited by spaces, 
to improve compatibility with GNU as.

Based on a patch by PaX Team.

Fixed assertion failures on non-Darwin and added additional test cases.

8926dd6aeb Make MapVector a bit more expensive but harder to misuse. We now only 
provide insertion order iteration, instead of the old option of
DenseMap order iteration over keys and insertion order iteration over
values.
This is implemented by keeping two copies of each key.

13bd00c244 InlineCost: Make TotalAllocaSizeRecursiveCaller unsigned to avoid sign-compare warnings.

f6de6e1e82 Prevent inlining of callees which allocate lots of memory into a recursive caller. 
Example:

void foo() {
 ... foo();   // I'm recursive!

  bar();
}

bar() {  int a[1000];  // large stack size }

eedf4ffbcb Refactor Record* by-ID comparator to Record.h 
This is a generally useful utility; there's no reason to have it hidden
in CodeGenDAGPatterns.cpp.

Also, rename it to fit the other comparators in Record.h

e91b4521bf When creating MCAsmBackend pass the CPU string as well. In X86AsmBackend 
store this and use it to not emit long nops when the CPU is geode which
doesnt support them.

6cba50cbb4 Replaced ReInitMCSubtargetInfo with InitMCProcessor. 
Now where we used to call ReInitMCSubtargetInfo, we actually recompute
the same information as InitMCSubtargetInfo instead of only setting
the feature bits.

b761721812 Merge into undefined lanes under -new-coalescer. 
Add LIS::pruneValue() and extendToIndices(). These two functions are
used by the register coalescer when merging two live ranges requires
more than a trivial value mapping as supported by LiveInterval::join().

The pruneValue() function can remove the part of a value number that is
going to conflict in join(). Afterwards, extendToIndices can restore the
live range, using any new dominating value numbers and updating the SSA
form.

Use this complex value mapping to support merging a register into a
vector lane that has a conflicting value, but the clobbered lane is
undef.
