Benjamin Kramer 4d050b6f85 Lazily allocate DenseMaps.
This makes lookup slightly more expensive but it's worth it, unused
DenseMaps are common in LLVM code apparently.

1% speedup on clang -O3 bzip2.c
4% speedup on clang -O3 oggenc.c (Release build of clang on i386/linux)

Anton Korobeynikov a9ff8576fb Normalize target triple passed out of driver. Basically this means
that at cc1 level we will always have normalized triple and thus can
provide necessary default based on e.g. environment value (e.g. for
"arm-eabi" triple, etc.)

NAKAMURA Takumi 98835748e3 test/CodeGen/2008-07-17-no-emit-on-error.c: Use LLVM's opt instead of "test(1)" for Mingw MSYS.

Cameron Zwarich 13c885d193 Fix PR9398 - 10% of llc compile time is spent in Value::getNumUses. This reduces

1.8% of total llc time.

Andrew Trick 641e2d4f8c Increased the register pressure limit on x86_64 from 8 to 12
regs. This is the only change in this checkin that may affects the
default scheduler. With better register tracking and heuristics, it
doesn't make sense to artificially lower the register limit so much.

Added -sched-high-latency-cycles and X86InstrInfo::isHighLatencyDef to
give the scheduler a way to account for div and sqrt on targets that
don't have an itinerary. It is currently defaults to 10 (the actual
number doesn't matter much), but only takes effect on non-default
schedulers: list-hybrid and list-ilp.

Added several heuristics that can be individually disabled for the
non-default sched=list-ilp mode. This helps us determine how much
better we can do on a given benchmark than the default
scheduler. Certain compute intensive loops run much faster in this
mode with the right set of heuristics, and it doesn't seem to have
much negative impact elsewhere. Not all of the heuristics are needed,
but we still need to experiment to decide which should be disabled by
default for sched=list-ilp.

Nick Lewycky 9719a719c7 Thread comparisons over udiv/sdiv/ashr/lshr exact and lshr nuw/nsw whenever
possible. This goes into instcombine and instsimplify because instsimplify

Douglas Gregor 250ffb1fcb When we're deserializing a template parameter declaration, temporarily
use the translation unit as its declaration context, then deserialize
the actual lexical and semantic DeclContexts after the template
parameter is complete. This avoids problems when the DeclContext
itself (e.g., a class template) is dependent on the template parameter
(e.g., for the injected-class-name).

Jakob Stoklund Olesen 4b598e156a Compute the constraints for global live range splitting from an interference pattern.
This simplifies the code and makes it faster too.

The interference patterns are saved for each candidate register. It will be

Greg Clayton fc7117ae93 Added a DynamicLoaderStatic plug-in that will act as a static dynamic loader.
It will just load all files exactly where the files state they are (file
addresses == load addresses). This is used when the llvm::Triple::OSType is
set to llvm::Triple::UnknownOS or llvm::Triple::NoOS.

Argyrios Kyrtzidis 11e6f0a6c3 Currently we can only remap a file by creating a MemoryBuffer and replacing the file contents with it.
Allow remapping a file by specifying another filename whose contents should be loaded if the original
file gets loaded. This allows to override files without having to create & load buffers in advance.
