Updated to reflect MachRegs.Addr to MachRegs.Address renaming; various x86 bug fixes

Updated to reflect that MachRegs.Addr has been renamed to Address to avoid needless conflict with GlaExts

Updated to reflect MachRegs.Addr to MachRegs.Address renaming; x86: Hp and HpLim are located relative to BaseReg, not StorageMgrInfo

Updated to reflect MachRegs.Addr to MachRegs.Address renaming; x86 shift instructions need special treatment to get at %cl; added DEBUG msg if x86 MOV %r,%r instruction generated

Updated to reflect MachRegs.Addr to MachRegs.Address renaming; fixed incorrect handling of x86 shift instructions (second operand can be *both* immediate and register(ecx))

import MachRegs unconditionally

Added flag opt_UnfoldingKeenessFactor; new (internal) function: lookup_def_float

Default for uNFOLDING_KEENESS_FACTOR (2.0) added; uNFOLDING_OVERRIDE_THRESHOLD removed

Bargain multiplier opt_UnfoldingKeenessFactor added to discount computation

Removed use of opt_CompilingGhcInternals

Drop CoreUnfold.mkUnfolding import

Added comment on special parser handling of non-qualified gtycons

Added type signatures

Drop use of opt_CompilingGhcInternals

Refrain from doing let-to-case conversion on binders with RHS in whnf

Drop use of opt_CompilingGhcInternals

Latest batch of changes.  Merge SRT and Tag fields in the info table,
now that there isn't a bytecode pointer there.

first cut at header files for new RTS

remove OmitDefaultInstanceMethods (unused).

Remove section about -fshow-pragma-name-errs.  This option is
unsupported, and unnecessary, since GHC can always find the
information it needs.

Remove crufty options.

mangler fix.

protect $$s for bash.

fix a bunch of out-of-date things, plus apply some patches for broken
\indexes and \items from Sven Panne.

add a few more index entries.

knock the section on warnings into shape.

add opt_WarnMissingMethods.

oops, correct a comment.

move -fwarn-incomplete-patterns into -W (it's not as likely to
indicate an error as -fwarn-overlapping-patterns), and add
-fwarn-unused-names to -W in case it gets implemented one day.

polymorphic recursion/space leak test

make the RAWCPP test a little more sensible.

Test for CC and GCC before finding CPP, since GNUCPP depends on
finding GCC to do the right thing.

Add description of how to set heap/stack sizes by default using the
defaultHook hook thingy.

release notes for upcoming releases

new test for type-synonym-arity bug (fixed in TcMonoType.lhs v1.19)

Simon's fix for type synonym arities.  The arity of a synonym must by
less than or eqaul to the number of arguments supplied (test
typecheck/should_compile/tc093.hs).

reverse the sense of -fwarn-incomplete-patterns and
-fwarn-overlapped-patterns, these are now added automatically by the
driver if necessary.

add -Wnot, -W and -Wall flags.

remove stuff to do with -user-prelude: it's not used anywhere, and not
documented.
