change EH related stuff (other than EH_LABEL) to use MCSymbol
...
instead of label ID's. This cleans up and regularizes a bunch
of code and makes way for future progress.
Unfortunately, this pointed out to me that JITDwarfEmitter.cpp
is largely copy and paste from DwarfException/MachineModuleInfo
and other places. This is very sad and disturbing. :(
One major change here is that TidyLandingPads moved from being
called in DwarfException::BeginFunction to being called in
DwarfException::EndFunction. There should not be any
functionality change from doing this, but I'm not an EH expert.

keep an MCContext reference handy, and cleans up the TargetRegistry

Change ARM ld/st multiple instructions to have variant instructions for

writebacks to the address register. This gets rid of the hack that the
first register on the list was the magic writeback register operand. There
was an implicit constraint that if that operand was not reg0 it had to match
the base register operand. The post-RA scheduler's antidependency breaker
did not understand that constraint and sometimes changed one without the
other. This also fixes Radar 7495976 and should help the verifier work
better for ARM code.
There are now new ld/st instructions explicit writeback operands and explicit
constraints that tie those registers together.

- The implementation is currently very brain dead and inefficient, but I have a

- The good news is, it works and correctly assembles 403.gcc (when built with
Clang, at '-Os', '-Os -g', and '-O3'). Even better, at '-Os' and '-Os -g',
the resulting binary is exactly equivalent to that when built with the system
assembler. So it probably works! :)

When outputing a non-lazy pointer for a stub, we may need to fill in the value
...
for the NLP because the object it's pointing to may be internal to the file.
This seems counter-intuitive, but bear with me. When we place the LSDA into the
TEXT section, the type info pointers need to be indirect and pc-rel. We
accomplish this by using NLPs. However, sometimes the types are local to the
file. GCC gets around this by not using a NLP in this case, but a "regular"
indirection like this:
GCC_except_tbl:
.long Lfoo-.
__ZTIA: @ This is local
...
Lfoo:
.long __ZTIA
LLVM prefers NLPs on Darwin. In fact, it's more optimal for load performance to
use them.

Add a couple more heuristics to neuter machine cse some more.
...
1. Be careful with cse "cheap" expressions. e.g. constant materialization. Only cse them when the common expression is local or in a direct predecessor. We don't want cse of cheap instruction causing other expressions to be spilled.
2. Watch out for the case where the expression doesn't itself uses a virtual register. e.g. lea of frame object. If the common expression itself is used by copies (common for passing addresses to function calls), don't perform the cse. Since these expressions do not use a register, it creates a live range but doesn't close any, we want to be very careful with increasing register pressure.
Note these are heuristics so machine cse doesn't make register allocator unhappy. Once we have proper live range splitting and re-materialization support in place, these should be evaluated again.
Now machine cse is almost always a win on llvm nightly tests on x86 and x86_64.

Try to keep the cached inliner costs around for a bit longer for big functions.
...
The Caller cost info would be reset everytime a callee was inlined. If the
caller has lots of calls and there is some mutual recursion going on, the
caller cost info could be calculated many times.
This patch reduces inliner runtime from 240s to 0.5s for a function with 20000
small function calls.
This is a more conservative version of r98089 that doesn't break the clang
test CodeGenCXX/temp-order.cpp. That test relies on rather extreme inlining
for constant folding.

Try to keep the cached inliner costs around for a bit longer for big functions.
...
The Caller cost info would be reset everytime a callee was inlined. If the
caller has lots of calls and there is some mutual recursion going on, the
caller cost info could be calculated many times.
This patch reduces inliner runtime from 240s to 0.5s for a function with 20000
small function calls.

The ARM EH experiment worked!
...
Place the LSDA into the TEXT section for ARM platforms. This involves making the
encoding indirect, pcrel, and sdata4 instead of an absolute pointer. The
references to the type infos are then non-lazy pointers. Revision 98019 changed
the encoding of non-lazy pointers to add the symbol to the non-lazy pointer
definition if it's a local symbol (otherwise, it's external and set to '0' so
that the loader can adjust it to the real value). This paved the way for this
change to work on ARM.

Disable physical register coalescing when the number of live ranges for the

std::upper_bound may be log(N), but for sufficiently large live intervals, it

function calls. The generated code is different, but not significantly worse -
the allocator hints are almost as good as physreg coalescing anyway.
