RegisterPressure API. Add support for physical register units.

At build-time register pressure was always computed in terms of
register units. But the compile-time API was expressed in terms of
register classes because it was intended for virtual registers (and
physical register units weren't yet used anywhere in codegen).

Now that the codegen uses physreg units consistently, prepare for
tracking register pressure also in terms of live units, not live
registers.

[msan] Change linkage type of __msan_track_origins.

LinkOnceODRLinkage globals may be removed in GlobalOpt if not used in the
current module.

[msan] Initialize callbacks in runOnFunction as opposed to doInitialization.

This mirrors the change in ASan & TSan done in r168864.

- Added calls to doInitialization/doFinalization to immutable passes
- fixed ordering of calls to doFinalization to be the reverse of the pass run order due to potential dependencies
- fixed machine module info to operate in the doInitialization/doFinalization model, also fixes some FIXMEs

Added a option to the disassembler to print immediates as hex.

This is for the lldb team so most of but not all of the values are
to be printed as hex with this option.  Some small values like the
scale in an X86 address were requested to printed in decimal
without the leading 0x.

There may be some tweaks need to places that may still be in
decimal that they want in hex.  Specially for arm.  I made my best
guess.  Any tweaks from here should be simple.

I also did the best I know now with help from the C++ gurus
creating the cleanest formatImm() utility function and containing
the changes.  But if someone has a better idea to make something
cleaner I'm all ears and game for changing the implementation.

Remove unused MachineInstr constructors.

A MachineInstr can only ever be constructed by CreateMachineInstr() and
CloneMachineInstr(), and those factories don't use the removed
constructors.

Try to unbreak the build on hosts that don't transitively pull in a definition for int64_t.

Also use the portable (ugly) format string macros, for MSVC compatibility.

Adjust JIT target triple on OS X to match the current architecture.

For OS X builds, we generate one version of config.h but then build for
multiple architectures.  This means that the LLVM_HOSTTRIPLE setting may have
the wrong architecture.  Adjust it dynamically to match the current
architecture.  <rdar://problem/12715470>

Remove the non-const getInst accessor. It wasn't being used, and isn't very
good for enacpsulation anyway.

Use multiclass to define store instructions with base+immediate offset
addressing mode and immediate stored value.

Updates to Win64EH.h structures.

Change member types of RuntimeFunction and UnwindInfo from uint64_t to
uint32_t:
These members represent addresses. According to MSDN, they are image
relative, that is, they are 32-bit offsets from the starting address
of the image that contains the function table entry.
See MSDN for more information:
RUNTIME_FUNCTION: http://msdn.microsoft.com/en-us/library/ft9x1kdx.aspx
UNWIND_INFO: http://msdn.microsoft.com/en-us/library/ddssxxy8.aspx

Make Win64.h platform-neutral:
The standard types unit8_t, uint16_t and uint32_t are replaced with
their counterparts from Endian.h. Accessor functions are introduced to
replace bit fields.

Add dump of Win64 EH unwind data.

The new command line option -unwind-info dumps the Win64 EH unwind
data to the console. This is a nice feature if you need to debug
generated EH data (e.g. from LLVM). Includes a test case.
