d8149c1bef PTX: Always use registers for return values, but use .param space for device 
parameters if SM >= 2.0

- Update test cases to be more robust against register allocation changes
- Bump up the number of registers to 128 per type
- Include Python script to re-generate register file with any number of
  registers

5417eed201 Support: make floating-exception header private 
It has only one user. This eliminates the last include of
config.h from the public headers -- ideally, config.h
shouldn't even be installed by `make install` anymore.

4e5885dc0f Don't include config.h in public headers 
Replace it with llvm-config.h, which defines a subset of
config.h's macros "so that they can be in exported headers 
and won't override package specific directives", e.g.,
PACKAGE_NAME.

Endian.h wasn't using any macros at all though, so just delete
the include there instead.

9dbbd87938 Move more logic to shouldTailDuplicate and only duplicate regular bb before

keeps the previous improvements to sunspider.

f2a58425cd lit support for REQUIRES: asserts. 
Take #2. Don't piggyback on the existing config.build_mode. Instead,
define a new lit feature for each build feature we need (currently
just "asserts"). Teach both autoconf'd and cmake'd Makefiles to define
this feature within test/lit.site.cfg. This doesn't require any lit
harness changes and should be more robust across build systems.
