Allow targets to customize the default behavior of the generic loop unrolling
transformation. This will be used by the PowerPC backend when targeting the A2
core (which is in-order with a deep pipeline), and using more aggressive
defaults is important.

Definition of DIRef used to require the full definition of DIType because
of usage of DIType::isType in DIRef::resolve. We now use DIDescriptor::isType
instead to remove the requirement and move definition of DIRef before DIType.

With this, we can move the definition of DIType::getContext to the header
file.

It works with clang, but GCC has different rules so we can't make all of those
hidden. This reverts commit r190534.

 - This is a work-in-progress and all details are subject to change, but I am
   trying to build up support for allowing lit to be used as a driver for
   performance tests (or other tests which might want to record information
   beyond simple PASS/FAIL).

Cuts down the bloat in the AArch64 asm writer a bit.

[mips][msa] Added test cases that were supposed to be part of r190507, r190509, r190512, and r190518.

llvm-svn: 190522

[mips][msa] Added support for matching mulv, nlzc, sll, sra, srl, and subv from normal IR (i.e. not intrinsics)

llvm-svn: 190518

Otherwise SequenceToOffsetTable will sort by pointer and becomes non-deterministic.

llvm-svn: 190514

[mips][msa] Added support for matching fadd, fdiv, flog2, fmul, frint, fsqrt, and fsub from normal IR (i.e. not intrinsics)

llvm-svn: 190512

This reflects the common use case of nativizing a prepared path. The existing
version invokes undefined behavior if input = output, add an assert to catch
that case.

The corresponding intrinsic is now lowered into equivalent IR (ISD::ADD) before instruction selection.

The elements of the operands should be half the width of the elements of
the result.

address space 0.

[python-bindings] Added support for getting/setting operands of values and getting the number of operands of a value.

Also in the process did some cleanups for BasicBlock.

llvm-svn: 190477

[python-bindings] Added support for iterating over a basic blocks instructions, getting their name/dumping them, f/b iteration.

Tests are included.

llvm-svn: 190475

[python-bindings] Added support for iterating over a function's basic blocks, dumping/getting names of those bb, f/w iteration.

Tests are included.

llvm-svn: 190473

llvm-svn: 190472

[python-bindings] Added support for getting a module's functions, iterating f/b over said functions, dumping/print name of functions.

Tests are included as well.

llvm-svn: 190471

YAMLIO printed a string as is without quotes unless it contains a newline
character. That did not suffice. We also need to quote a string if it starts
with a backquote, quote, double quote or atsign, or it's the empty string.

In some cases (e.g. when a build system pipes stderr) the Windows console
API cannot be used to color output. For these, provide a way to switch to
ANSI escape codes. This is required for Clang's -fansi-escape-codes option.

llvm-svn: 190460

llvm-svn: 190459

[python-bindings] Added code for loading a module from bitcode, getset its datalayout, getset its target, dump it, print it to a file.

llvm-svn: 190458

[python-bindings] Added bindings for LLVMContextRef and a test for creating a new context or getting the global context.
