This patch migrates the ffs* optimizations from the simplify-libcalls
pass into the instcombine library call simplifier.

  - Widespread trailing space removal
  - A dash of OCD spacing to block align enums
  - joined a line that probably needed 80 cols a while back

Roman Divacky. I added the bits in MCDwarf.cpp and the test.

Remove duplicate check of LimitFloatPrecision. It was already checked earlier before IsExp10 could be set to true.

Remove redundant calls to getCurDebugLoc in visitIntrinsicCall. It's already called at the start of the function and captured in a local variable.

Necessary to give disassembler users (like darwin's otool) a possibility to
dlopen libLTO and still initialize the required LLVM bits. This used to go
through libMCDisassembler but that's a gross layering violation, the MC layer
can't pull in functions from the targets. Adding a function to libLTO is a bit
of a hack but not worse than exposing other disassembler bits from libLTO.

Fixes PR14362.

The implementations already diverged a bit, merge them back together.

The last remaining bit is "bcl 20, 31, AnonSymbol", which I couldn't find the
instruction definition for. Only whitespace changes in assembly output.

[asan/tsan] get rid of kPageSize completely in favor of GetPageSizeCached(). This makes the code friendly to more platforms

llvm-svn: 168537

We now store the Register and Offset directly. MachineLocation is gone (from
this file)!

This untangles the switch cases of the old Move and RelMove opcodes a bit
and makes it clear how to add new instructions.

llvm-svn: 168533

Give MCCFIInstruction a single, private constructor and add helper static
methods that create each type of cfi instruction. This is is preparation
for changing its representation. The representation with a pair
MachineLocations older than MC and has been abused quiet a bit to support
more cfi instructions.

It can delete the block, and the loop continues on free'd memory.
No change in output. Found by valgrind.
