Owen Anderson fa8b2ea41b Speed up addRegisterDead by adding more fast checks before performing the expensive
subregister query, and by increasing the size of the subregister hashtable so
that there are fewer collisions.

Evan Cheng 4a898c0b11 TargetRegisterDesc::Name field is the same as the abstract register name. There is no need for targets to specify register names in addition to their AsmName's.

Owen Anderson 1760b92d27 Implement suggestions from Chris:
- Use a more accurate heuristic for the size of the hashtable.
  - Use bitwise and instead of modulo since the size is a power of two.
  - Use new[] instead of malloc().

Owen Anderson 49cce257ae Replace the dynamically computed std::set lookup method for subregisters with a hashtable-based
version that is computed by tblgen at the time LLVM is compiled.

Dale Johannesen a2de8eab61 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.)

Duncan Sands 13237ac3b9 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).

Bill Wendling c24ea4fb41 Change "Name" to "AsmName" in the target register info. Gee, a refactoring tool
would have been a Godsend here!

Bill Wendling a7d1ed4c98 Some platforms use the same name for 32-bit and 64-bit registers (like
%r3 on PPC) in their ASM files. However, it's hard for humans to read
during debugging. Adding a new field to the register data that lets you
specify a different name to be printed than the one that goes into the
ASM file -- %x3 instead of %r3, for instance.

Anton Korobeynikov 4edfea438a Use TableGen to emit information for dwarf register numbers.
This makes DwarfRegNum to accept list of numbers instead.

Chandler Carruth 7132e00de7 This is the patch to provide clean intrinsic function overloading support in LLVM. It cleans up the intrinsic definitions and generally smooths the process for more complicated intrinsic writing. It will be used by the upcoming atomic intrinsics as well as vector and float intrinsics in the future.
This also changes the syntax for llvm.bswap, llvm.part.set, llvm.part.select, and llvm.ct* intrinsics. They are automatically upgraded by both the LLVM ASM reader and the bitcode reader. The test cases have been updated, with special tests added to ensure the automatic upgrading is supported.

Chuck Rose III 1a39a2d13d VStudio compiler errors and placing Function*->ExFunc map under ManagedStatic control.
This commit fixes two things.  One is a pair of VStudio compiler errors stemming from variables
which defined within the for loop statement and also within the body of the for loop.  I fixed these 
by renaming one of the two variables.  Additionally, I've made the Function*->ExFunc map in 
ExternalFunctions.cpp a ManagedStatic object, so that cleanup will be done on llvm_shutdown.  In repeated
uses of the interpreter, where the same Function* address may get used for completely differnet functions,
this was causing a crash.
