2005804de6 - Re-apply 52748 and friends with fix. GetConstantStringInfo() returns an empty string for ConstantAggregateZero case which surprises selectiondag. 
- Correctly handle memcpy from constant string which is zero-initialized.

6f260767ec Revert (52748 and friends): 
Move GetConstantStringInfo to lib/Analysis. Remove
string output routine from Constant. Update all
callers. Change debug intrinsic api slightly to
accomodate move of routine, these now return values
instead of strings.

This unbreaks llvm-gcc bootstrap.

6b3b22747a Add a new version of Module::getFunction that takes a const char* instead 
of a std::string.  This avoids copying the string to the heap in common
cases.  Patch by Pratik Solanki!

968d4e2444 Use push_back rather than operator[], which is incorrect in this cases. Unfortunately, this slow the testcase down a little bit, 
but only marginally.

673cae8561 In ConstantArray::getAsString(), we know the size of the resultant string in advance so we can pre-allocate it and just fill in 
the entries.  This improves the time for the AsmPrinter on InstructionCombining.cpp from 0.4248s to 0.3370s.

68f8fbdac4 Re-apply 52002, allowing the verifier to accept non-MRV struct return 
types on functions, with adjustments so that it accepts both
new-style aggregate returns and old-style MRV returns, including those
with only a single member.

d634afe3aa Wrap MVT::ValueType in a struct to get type safety 
and better control the abstraction.  Rename the type
to MVT.  To update out-of-tree patches, the main
thing to do is to rename MVT::ValueType to MVT, and
rewrite expressions like MVT::getSizeInBits(VT) in
the form VT.getSizeInBits().  Use VT.getSimpleVT()
to extract a MVT::SimpleValueType for use in switch
statements (you will get an assert failure if VT is
an extended value type - these shouldn't exist after
type legalization).
This results in a small speedup of codegen and no
new testsuite failures (x86-64 linux).

ac5c3382fe IR, bitcode reader, bitcode writer, and asmparser changes to 
insertvalue and extractvalue to use constant indices instead of

interested.
