Exclude the bit-field bits from string hash codes. String hash codes
...
are always odd if the bit-field bits are included.
Modified a couple of debugger tests that relied on the ordering of
elements in descriptor arrays. Descriptor arrays are sorted by
hash-code values, so the order changes if we change the hash code.

Don't defer the stack check failure code. It is a CallStub, which will be a single 5 byte call instruction. This should cause equivalent code size now, but opens up the opportunity to make one of the most common jcc's to use short encoding in the future.

Defer the writing of the source position data to the relocation information
...
until a possible debug break location is reached. Currently this is call sites
with calls to code objects and JS return. Source position information in the
code therefore no longer refers to the "first" instruction generated for a
given source position (which was not the case defered code anyway) but to the
first break location after that source position was passed (again defered code
always start with source position information). This doesn't make a difference
for the debugger as it will always be stopped only at debug break locations.
However, this makes the life of the peep-hole optimizer much easier as many
oportunities for posh/pop eliminations where previosly blocked by relocation
information already written to the code object.
Two types of source positions are still collected. Statement positions indicate
the position of the start of the statement leading to this code and (plain)
positions indicate other places typically call sites to help indicate current
position in backtraces. The two different types of positions are also used to
distinguish between step next and step in.
Runs all the tests (including debugger tests) as before.
Moved the checking for the FLAG_debug_info to one place.
I will do the same changes to the ARM codegenerator in a seperate changelist.

This is a new static flag system, designed to have all flags in a central place, and compiled into the binary without requiring static constructors for registration. All flags are moved out of the specific modules and into flags.defs, with different sections for debug, release, etc. The flag variables are always defined. For example, a debug flag in release mode still exists, but is read only and set to the default value.
