Add a new pass on machine instructions to optimize away PHI cycles that
...
reduce down to a single value. InstCombine already does this transformation
but DAG legalization may introduce new opportunities. This has turned out to
be important for ARM where 64-bit values are split up during type legalization:
InstCombine is not able to remove the PHI cycles on the 64-bit values but
the separate 32-bit values can be optimized. I measured the compile time
impact of this (running llc on 176.gcc) and it was not significant.

The previous fix of widening divides that trap was too fragile as it depends on custom

lowering and requires that certain types exist in ValueTypes.h. Modified widening to
check if an op can trap and if so, the widening algorithm will apply only the op on
the defined elements. It is safer to do this in widening because the optimizer can't

Previously spill registers, whose def indexes are not defined, would sometimes be improperly marked as coalescable with conflicting registers.

Rearrange handling of jump tables. Highlights:
...
1. MachineJumpTableInfo is now created lazily for a function the first time
it actually makes a jump table instead of for every function.
2. The encoding of jump table entries is now described by the
MachineJumpTableInfo::JTEntryKind enum. This enum is determined by the
TLI::getJumpTableEncoding() hook, instead of by lots of code scattered
throughout the compiler that "knows" that jump table entries are always
32-bits in pic mode (for example).
3. The size and alignment of jump table entries is now calculated based on
their kind, instead of at machinefunction creation time.
Future work includes using the EntryKind in more places in the compiler,
eliminating other logic that "knows" the layout of jump tables in various
situations.

Add the ability for MCStreamer to emit comments on the same line as directives.
...
Switch over the asm-verbose comment for double values to use it. We now get:
_x:
.long 343597384 ## double 1.231200e+02
.long 1079953326
For example, note that the comment is on the same line as the .long. Woo.

Stop building RTTI information for *most* llvm libraries. Notable

missing ones are libsupport, libsystem and libvmcore. libvmcore is

EH, we can switch it off.
This #if 0's out 3 unit tests, because gtest requires RTTI information.
Suggestions welcome on how to fix this.
