4eafe10945 Don't force relaxation of AdvanceLoc instructions on OS X. gdb is happy with 
the smaller encoding and this cuts 270336 bytes from a release version of
clang and 1246272 bytes from a debug build.

c06b511eba ExecutionEngine: push TargetMachine creation into clients 
In particular, into EngineBuilder. This should only impact
the private API between the EE and EB classes, not external
clients, since JITCtor and MCJITCtor are both protected members.

who used this flag, and it now emits CFI and doesn't emit this anymore. All
other targets left this flag "false".

597a7664e1 Producing a DW_FORM_addr for DW_AT_stmt_list is probably correct, but 
it is both inefficient and unexpected by dwarfdump. Change to
a DW_FORM_data4.

While in here, change the predicate name to reflect that the position
is not really absolute (it is an offset), just that the linker needs a
relocation.

ad20681cde Implement some basic simplifications involving min/max, for example

by far the most common simplifications (of the -instsimplify kind)
that occur in the testsuite and aren't caught by -std-compile-opts.

8e33095cd4 Add a SlotIndexes::insertMachineInstrInMaps to insert the instruction after any null indexes. 
This makes a difference if a live interval is referring to a deleted
instruction. It can be important to insert an instruction before or after a
deleted instruction to avoid interference.

debd7e4e8b Simplify the handling of pcrel relocations on ELF. Now we do the right thing 
for all symbol differences and can drop the old EmitPCRelSymbolValue
method.

This also make getExprForFDESymbol on ELF equal to the one on MachO, and it
can be made non-virtual.

4034e14985 teach GVN to widen integer loads when they are overaligned, when doing an 
wider load would allow elimination of subsequent loads, and when the wider
load is still a native integer type.  This eliminates a ton of loads on 
various benchmarks involving struct fields, though it is somewhat hobbled
by clang not being very aggressive about field alignment.

This is yet another step along the way towards resolving PR6627.
