b746b82113 Add back the capability to include nul characters in strings with
GetConstantStringInfo.  This will hopefully restore llvm-gcc to 
happy bootstrap land.

25b825b3b8 Tweak IRBuilder to explicitly call the setName(const char*) method on Value
instead of passing the name into the instruction ctors.  Since most 
instruction ctors take their name as an std::string, this avoids copying the
string to the heap and a malloc and free.

Patch by Pratik Solanki!

b5dae00325 Fixes the last x86-64 test failure in compat.exp:
<16 x float> is 64-byte aligned (for some reason),
which gets us into the stack realignment code.  The
computation changing FP-relative offsets to SP-relative
was broken, assiging a spill temp to a location
also used for parameter passing.  This
fixes it by rounding up the stack frame to a multiple
of the largest alignment (I concluded it wasn't fixable
without doing this, but I'm not very sure.)

041cde26ea Add support for expanding PPC 128 bit floats.
For this it is convenient to permit floats to
be used with EXTRACT_ELEMENT, so I tweaked
things to allow that.  I also added libcalls
for ppcf128 to i32 forms of FP_TO_XINT, since
they exist in libgcc and this case can certainly
occur (and does occur in the testsuite) - before
the i64 libcall was being used.  Also, the
XINT_TO_FP result seemed to be wrong when
the argument is an i128: the wrong fudge
factor was added (the i32 and i64 cases were
handled directly, but the i128 code fell
through to some generic softening code which
seemed to think it was i64 to f32!).  So I
fixed it by adding a fudge factor that I
found in my breakfast cereal.
