270e075dec TargetLowering interface to set/get minimum block entries for jump tables. 
Provide interface in TargetLowering to set or get the minimum number of basic
blocks whereby jump tables are generated for switch statements rather than an
if sequence.

    getMinimumJumpTableEntries() defaults to 4.
    setMinimumJumpTableEntries() allows target configuration.

    This patch changes the default for the Hexagon architecture to 5
    as it improves performance on some benchmarks.

f8bd27333f Casting: assert that pointer arguments to isa<> are non-null. 
This silences several analyzer warnings within LLVM, and provides a slightly
nicer crash experience when someone calls isa<>, cast<>, or dyn_cast<> with
a null pointer.

8632457a1a DenseMap: assert that we have found a bucket before we try to insert into it. 
This silences literally dozens of analyzer warnings on LLVM (since DenseMap
is such a commonly-used class).

8172c32318 Add an --enable-backtraces option to configure to determine

for libraries that don't need backtrace information on a crash.

135898ebe3 ARM: Use a dedicated intrinsic for vector bitwise select. 
The expression based expansion too often results in IR level optimizations
splitting the intermediate values into separate basic blocks, preventing
the formation of the VBSL instruction as the code author intended. In
particular, LICM would often hoist part of the computation out of a loop.

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.

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.

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.
