4e9c54278e * the function result of constructors always is self, always is valid and is 
not stored in procdef.funcretsym -> fix check so that SSA is not performed
    on it in constructors when exit is used

07b2982e77 Don't do ARM FoldShiftLdrStr peephole optimization if there's an offset in the reference. 
Use UXTH+UXTB instructions instead of two shifts on processors that supports that.
Eliminate internalerror when constant pointers are typecast as arrays.

81517fdf70 Rerun peephole optimizers on the whole block 
Up until now if a peephole optimizer matched we've only restarted from
the current instruction. This patch restarts optimizations on the whole
block if the previous run had at least one match.

As this can take considerable time this will only be enabled if -O3 or
higher is specified.

1034503c5d fcl-db: bufdataset: improve rev.26604. do not use Field.SetData in BlobStream constructor, because SetData also calls Validate and generates deFieldChange. Which is too early in constructor. These events must be generated after data will be written (in fact deFieldChange is called in BlobStream destructor and Validate is not called in current implementation). 
Instead of Field.SetData I use direct write to record buffer.

57ff589ec7 Always set p to the next instruction after removing p from asml. 
Some time ago we introduced GetNextInstructionUsingReg, which might
return an instruction a couple of instructions away from our current
location. Most of the code then just returned the new instruction (hp1)
instead of the instruction following p. This could prevent the peephole
optimizer from finding possible optimizations.

8e6fcd876c fcl-db: bufdataset: when data are written to BLOB field (using TBufBlobStream) assign new write blob buffer to BLOB field in record buffer. So new data are there before Post.

c644503daf Add MovLdr2Ldr peephole optimizer for ARM 
The existing LdrLdr2LdrMov optimizer will generate a lot of
sequences like this:

ldr regA, [...]
mov regB, regA
ldr regB, [regB, ...]

this now gets changed to

ldr regA, [...]
ldr regB, [regA, ...]

this saves an instruction and might open up more possibilities for the load scheduler.

77d12f61a2 Handle LDRD and STRD correctly in RegInInstruction for ARM 
LDRD and STRD only have the first even numbered register in their instruction operands,
this additional code will also check for the register following it.
Example:
  ldrd r0, [r13]

The old code will only detect r0 as in use, not the implicit r1.
