Fix ExpandShiftWithUnknownAmountBit, which was completely bogus.
Pointed out by Javier Martinez (who also provided a patch).  Since
this logic is not used on (for example) x86, I guess nobody noticed.
Tested by generating SHL, SRL, SRA on various choices of i64 for all
possible shift amounts, and comparing with gcc.  Since I did this on
x86-32, I had to force the use of ExpandShiftWithUnknownAmountBit.
What I'm saying here is that I don't have a testcase I can add to the

Fix PR5391: support early clobber physical register def tied with a use (ewwww)
- A valno should be set HasRedefByEC if there is an early clobber def in the middle of its live ranges. It should not be set if the def of the valno is defined by an early clobber.
- If a physical register def is tied to an use and it's an early clobber, it just means the HasRedefByEC is set since it's still one continuous live range.
- Add a couple of missing checks for HasRedefByEC in the coalescer. In general, it should not coalesce a vr with a physical register if the physical register has a early clobber def somewhere. This is overly conservative but that's the price for using such a nasty inline asm "feature".

Use CFG connectedness as a secondary sort key when deciding the order of copy coalescing.

This means that well connected blocks are copy coalesced before the less connected blocks. Connected blocks are more difficult to
coalesce because intervals are more complicated, so handling them first gives a greater chance of success.

Add a soft link so that in an apple style build we can find libLTO.dylib.

Add two CMake flags LLVM_ENABLE_PEDANTIC and LLVM_ENABLE_WERROR,
PEDANTIC defaults to ON and WERROR default to off.

Also add MSVC warnings. To disable warnings add the flags
LLVM_ENABLE_WARNINGS (default on).

For VMOV (immediate), make some of the encoding bits (cmode and op) unspecified.
For VMOVv*i[16,32], op bit is don't care, and some cmode bits vary depending on
the immediate values.

Fix typos in comments.

New virtual registers created for spill intervals should inherit allocation hints from the original register.

This helps us avoid silly copies when rematting values that are copied to a physical register:

leaq _.str44(%rip), %rcx
movq %rcx, %rsi
call _strcmp

becomes:

leaq _.str44(%rip), %rsi
call _strcmp

The coalescer will not touch the movq because that would tie down the physical register.

Reprioritize tests for tail duplication to be aggressive about indirect
branches even when optimizing for code size.  Unless we find evidence to the
contrary in the future, the special treatment for indirect branches does not
have a significant effect on code size, and performance still matters with -Os.
