9f24a077bd ADd support for select instructions

b06f103d0c SPECIFY a target data to initialize the CBE target with. Until now we have
been using the default target data layout object to lower malloc instructions,
causing us to allocate more memory than we needed!  This could improve the
performance of the CBE generated code substantially!

05b15fb075 TargetCacheInfo has been removed; its only uses were to propagate a constant
(16) into certain areas of the SPARC V9 back-end. I'm fairly sure the US IIIi's
dcache has 32-byte lines, so I'm not sure where the 16 came from. However, in
the interest of not breaking things any more than they already are, I'm going
to leave the constant alone.

3799eec3cf Fixes for PR258 and PR259.
Functions with linkonce linkage are declared with weak linkage.
Global floating point constants used to represent unprintable values
(such as NaN and infinity) are declared static so that they don't interfere
with other CBE generated translation units.

2bcab1f900 Fix some unexpected fallout from the config.h changes. Because the CBE no
longer was getting this #include, it always fell back on the less precise
floating point initializer values, causing some testsuite failures.

e42cde2a14 Now that the lowerinvoke pass inserts calls to llvm.setjmp/llvm.longjmp, some
hacks can be banished.  Also, this gives us the opportunity to emit special code
for the setjmp/longjmps which alows the elimination of one GCC warning for every
setjmp/longjmp site (which is often THOUSANDS in C++ programs).  Yaay!

94f4f8ea10 Make the cwriter use the lowerinvoke pass so that it can either use "disabled exceptions" or
"expensive exceptions" controlled by an option.  Also refactor and eliminate a bunch of cruft.
This is a temporary solution and causes millions of warnings to pour out of programs that use
exceptions, but it should fix the problem with sparc and the 'write' declaration (PR190).
Subsequent changes will make this stink much less

01b2d61311 Fixed the CBE on Solaris/Sparc. We need to define the return value of
the write() system call because it returns 64 bits on Solaris 64 bit,
and an implicit return value of int says it returns 32 bits.
Admittedly, this is a bit of a hack.

c59c118e44 ISO 9899 7.13.2.1 (3) says that "[...] the values of objects of automatic
storage duration that are local to the function containing the invocation of the
[...] setjmp macro that do not have volatile-qualified type and have been
changed between the setjmp invocation and longjmp call are indeterminate."

As such, we have to mark all variables in a function that uses 'invoke' as
volatile.

This fixes PR77

5ef6ffd6c3 * Spell "necessary" correctly
* Print floating point values using C99 hexadecimal style FP if possible.
  This increases the number of floating point constants that may be emitted
  inline, and improves precision for global variable initializers which
  can not be emitted in integer form.

This fixes the Olden/Power benchmark with the CBE!!!!

9860e77110 * Be TBAA safe
* Fix isFPCSafeToPrint to find more constants safe to print, which it was
  failing because ftostr was padding with leading space characters.
* Scan the entire module for global constants instead of each function at a
  time.  This has the advantage of allowing us to emit constants at global
  scope instead of function scope.  This speeds FP programs quite a bit.

54f6032dae - Fixed name mangling conditions to handle 'linkonce' linkage type. In
particular, name mangling for GlobalValues only occurs when the linkage type is
internal or when the name must be mangled to avoid a collision.  See comments in
CWriter::getValueName for more information.

- 'inline' keyword is now emitted for functions with 'linkonce' linkage type.

- Fixed typos.

a8ab89e3da Fairly major change: emit fixed sized allocas in the entry block as a variable,
instead of a variable pointer and an alloca.  All accesses to the variable then
use the address-of operator to access it.  This plays better with the internal
GCC code generation phases, which bail early on functions which contain allocas.
It also makes the code a bit easier to read.

d1cf1b458a Fix cwriter to not output FP constants in ascii, output them in hex instead.
This fixes a number of FP precision problems, making the output of the
power benchmark closer to the right answer.

Unfortunately, this only addresses FP constants used directly in functions.
Constants referred to by global constants (such as an array of FP values)
aren't helped by this.  Until this happens power won't work.

2db41cd5de Another change that doesn't affect functionality. Since we are only looking
at types in the symbol table, only traverse the type plane, saving a loop nest.

it is a pointer type for which no name should be printed,
