- Put statistics in alphabetical order
- Don't use getZextValue when building TableInt, just use APInts
- Introduce Create{Z,S}ExtOrTrunc in IRBuilder.

systematically manage the alignment on loads and stores.

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.

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.

This silences literally dozens of analyzer warnings on LLVM (since DenseMap
is such a commonly-used class).

whether or not we want to print out backtrace information. Useful
for libraries that don't need backtrace information on a crash.

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.

Make the TargetPrefix setting one big setting instead of being spread out
everywhere. No functional change.

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.

Based on a patch by PaX Team.
Fixed assertion failures on non-Darwin and added additional test cases.

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.

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

store this and use it to not emit long nops when the CPU is geode which
doesnt support them.
