Use indirect calls in PowerPC JIT.
...
See PR5201. There is no way to know if direct calls will be within the allowed
range for BL. Hence emit all calls as indirect when in JIT mode.
Without this long-running applications will fail to JIT on PowerPC with a
relocation failure.

Fix the ValueMap copy constructor. The issue is that the map keys are value
...
handles with a pointer to the containing map. When a map is copied, these
pointers need to be corrected to point to the new map. If not, then consider
the case of a map M1 which maps a value V to something. Create a copy M2 of
M1. At this point there are two value handles on V, one representing V as a
key in M1, the other representing V as a key in M2. But both value handles
point to M1 as the containing map. Now delete V. The value handles remove
themselves from their containing map (which destroys them), but only the first
value handle is successful: the second one cannot remove itself from M1 as
(once the first one has removed itself) there is nothing there to remove; it
is therefore not destroyed. This causes an assertion failure "All references
to V were not removed?".

Many Thumb2 instructions can reference the full ARM register set (i.e.,
...
have 4 bits per register in the operand encoding), but have undefined
behavior when the operand value is 13 or 15 (SP and PC, respectively).
The trivial coalescer in linear scan sometimes will merge a copy from
SP into a subsequent instruction which uses the copy, and if that
instruction cannot legally reference SP, we get bad code such as:
mls r0,r9,r0,sp
instead of:
mov r2, sp
mls r0, r9, r0, r2
This patch adds a new register class for use by Thumb2 that excludes
the problematic registers (SP and PC) and is used instead of GPR
for those operands which cannot legally reference PC or SP. The
trivial coalescer explicitly requires that the register class
of the destination for the COPY instruction contain the source
register for the COPY to be considered for coalescing. This prevents
errant instructions like that above.

We do sometimes load from a too small stack slot when dealing with x86 arguments

This would never be a problem when the tied def was the only def which is the
usual case.

Simplifying use_iterators by dereferencing
is not a good idea. The codebase does not depend
in this any more, and it may introduce hidden
runtime cost. If you get compile errors, please
dereference your iterator before passing to cast<>

Also: please consider caching the result of
operator* and reusing that instead of dereferencing
many times.

Fix (at least) quadratic worst-case complexity in DominanceFrontier::splitBlock:
...
don't visit all blocks in the function, and don't iterate over the split blocks'
predecessor lists for each block visited.
Also, remove the special-case test for the entry block. Splitting the entry
block isn't common enough to make this worthwhile.
This fixes a major compile-time bottleneck which is exposed now that
LoopSimplify isn't being redundantly run both before and after
DominanceFrontier.

- Allow target to specify when is register pressure "too high". In most cases,
...
it's too late to start backing off aggressive latency scheduling when most
of the registers are in use so the threshold should be a bit tighter.
- Correctly handle live out's and extract_subreg etc.
- Enable register pressure aware scheduling by default for hybrid scheduler.
For ARM, this is almost always a win on # of instructions. It's runtime
neutral for most of the tests. But for some kernels with high register
pressure it can be a huge win. e.g. 464.h264ref reduced number of spills by
54 and sped up by 20%.

terrible in other ways. Since "GetInstSizeInBytes" is really
only there to support the JIT's "NeedsExactSize" hook (which
noone is using), just rip out the code. I will rip out the
NeedsExactSize hook next.

Add new RegionInfo pass.
...
The RegionInfo pass detects single entry single exit regions in a function,
where a region is defined as any subgraph that is connected to the remaining
graph at only two spots.
Furthermore an hierarchical region tree is built.
Use it by calling "opt -regions analyze" or "opt -view-regions".

Fix constant island pass's handling of tBR_JTr. The offset of the instruction does not have to be 4-byte aligned. Rather, it's the offset + 2 that must be aligned since the instruction expands into:
...
mov pc, r1
.align 2
LJTI0_0_0:
.long LBB0_14
This fixes rdar://8213383. No test case since it's not possible to come up with a suitable small one.
