Dan Gohman 4b2b48daba Make getTypeSizeInBits work correctly for array types; it should return
the number of value bits, not the number of bits of allocation for in-memory
storage.

Make getTypeStoreSize and getTypeAllocSize work consistently for arrays and
vectors.

Fix several places in CodeGen which compute offsets into in-memory vectors
to use TargetData information.

This fixes PR1784.

Douglas Gregor 0d5b0a1e5e ActOnPseudoDestructorExpr now performs all semantic analysis for
pseudo-destructor expressions, and builds the CXXPseudoDestructorExpr
node directly. Currently, this only affects pseudo-destructor
expressions when they are parsed, but not after template
instantiation. That's coming next...

Improve parsing of pseudo-destructor-names. When parsing the
nested-name-specifier and we hit the sequence of tokens X :: ~, query
the actual module to determine whether X is a type-name (in which case
the X :: is part of the pseudo-destructor-name but not the
nested-name-specifier) or not (in which case the X :: is part of the
nested-name-specifier).

Douglas Gregor e610adae17 Rework parsing of pseudo-destructor expressions and explicit
destructor calls, e.g., 

  p->T::~T

We now detect when the member access that we've parsed, e.g.,

  p-> or x.

may be a pseudo-destructor expression, either because the type of p or
x is a scalar or because it is dependent (and, therefore, may become a
scalar at template instantiation time). 

We then parse the pseudo-destructor grammar specifically:

  ::[opt] nested-name-specifier[opt] type-name :: ∼ type-name

and hand those results to a new action, ActOnPseudoDestructorExpr,
which will cope with both dependent member accesses of destructors and
with pseudo-destructor expressions.

This commit affects the parsing of pseudo-destructors, only; the
semantic actions still go through the semantic actions for member
access expressions. That will change soon.

John McCall 8ee376f08a Canonicalize parameter and return types before computing ABI info. Eliminates
a common source of oddities and, in theory, removes some redundant ABI
computations.  Also fixes a miscompile I introduced yesterday by refactoring
some code and causing a slightly different code path to be taken that
didn't perform *parameter* type canonicalization, just normal type
canonicalization;  this in turn caused a bit of ABI code to misfire because
it was looking for 'double' or 'float' but received 'const float'.

Dan Gohman 3860521406 When forming SSE min and max nodes for UGE and ULE comparisons, it's
necessary to swap the operands to handle NaN and negative zero properly.

Also, reintroduce logic for checking for NaN conditions when forming
SSE min and max instructions, fixed to take into consideration NaNs and
negative zeros. This allows forming min and max instructions in more
cases.

Chris Lattner df8a8a8c6f Change the scheduler from adding nodes in allnodes order
to adding them in a determinstic order (bottom up from 
the root) based on the structure of the graph itself.

This updates tests for some random changes, interesting
bits: CodeGen/Blackfin/promote-logic.ll no longer crashes.
I have no idea why, but that's good right?

CodeGen/X86/2009-07-16-LoadFoldingBug.ll also fails, but
now compiles to have one fewer constant pool entry, making
the expected load that was being folded disappear.  Since it
is an unreduced mass of gnast, I just removed it.

Bob Wilson 66e58ac742 Add an argument to PHITranslateValue to specify the DominatorTree. If this
argument is non-null, pass it along to PHITranslateSubExpr so that it can
prefer using existing values that dominate the PredBB, instead of just
blindly picking the first equivalent value that it finds on a uselist.
Also when the DominatorTree is specified, have PHITranslateValue filter
out any result that does not dominate the PredBB.  This is basically just
refactoring the check that used to be in GetAvailablePHITranslatedSubExpr
and also in GVN.

Despite my initial expectations, this change does not affect the results
of GVN for any testcases that I could find, but it should help compile time.
Before this change, if PHITranslateSubExpr picked a value that does not
dominate, PHITranslateWithInsertion would then insert a new value, which GVN
would later determine to be redundant and would replace.  By picking a good
value to begin with, we save GVN the extra work of inserting and then
replacing a new value.
