* Fixed header data positions for DJCOFF executables, they need adjustment by stub size.
* Fixed symbol values in DJCOFF executables, they must be absolute.
* Fixed missing oso_common flag on TExeOutput.commonObjSection, causing incorrect COFF relocations to this section.

target can be run in parallel, so "clean", "digest" and/or "dbdigest"
have to be run in separate make invocations if you wish to use -j for
running the testsuite
git-svn-id: trunk@21406 -
* Assign section indexes independent from symbol indexing.
* Fixed section flags not assigned while reading DJGPP object files.
* Fixed objData type for TDJCoffexeoutput.
* Fixed entry point address of DJGPP executables.
* Fixed filling exe section headers for DJGPP.

and if the result does not depend on the types of the arguments (to
prevent "qwordconst>int64const" being turned into
"int64(qwordconst)>int64const" and thereby potentially change the outcome)

simplified via typeconvnode (corrects resultdef of "qword(1) shl 33",
mantis #22133)
* simplify shl/shr nodes after their resultdef has been set, so the
resultdef used during simplify is set (fixes same expression as above
when it is calculated by an inline function)

and also use this code to trash local variables in inlined routines
o fixes mantis #22088
o makes it possible to also implement it for the jvm target in the future

method is only used anymore internally in cgobj.tcg and its descendants
* made tcg.g_indirect_sym_load() protected to ensure it stays that way

- removed empty destructor and checks for nil before .Free (they are done in tobject.free itself)
+ added COMDAT definitions.

type conversions (those should always re-interpret the raw bits),
except for variants (because those are sometimes generated internally)
-- done so that -gt code at the node tree level can insert explicit
typecasts to integer types without triggering overloaded explicit
typecast operators such as in tests/test/terecs14

Reorder unaligned Load sequence on ARM
The old version produced code like that:
ldrb rDEST, [rBASE]
ldrb rTemp, [rBASE, #1]
orr rDEST, rDEST, rTEMP lsl #8 (2 stall cycles)
ldrb rTemp, [rBASE, #2]
orr rDEST, rDEST, rTEMP lsl #16 (2 stall cycles)
ldrb rTemp, [rBASE, #3]
orr rDEST, rDEST, rTEMP lsl #24 (2 stall cycles)
This creates a lot of stall-cycles on ARM Implementations with load
delay slots like Marvel Kirkwood or Intel XScale. With the usual up to 2
stall-cycles this code requires a total of 13 cycles (7 instructions + 6 stall
cycles) in best case.
The new code uses a second temp register to avoid the stall cycles.
ldrb rDEST, [rBASE]
ldrb rTemp1, [rBASE, #1]
ldrb rTemp2, [rBASE, #2]
orr rDEST, rDEST, rTEMP1 lsl #8
ldrb rTemp1, [rBASE, #3]
orr rDEST, rDEST, rTEMP2 lsl #16
orr rDEST, rDEST, rTEMP1 lsl #24 (1 stall cycle)
The rescheduling and second register bring the total cycles down to 8.
If a later rescheduling should happen for the last orr it even can go
down to 7.
