the result of an inline asm copy can be an arbitrary VT that the register
...
class supports. In the case of vectors, this means we often get the wrong
type (e.g. we get v4f32 instead of v8i16). Make sure to convert the vector
result to the right type. This fixes CodeGen/X86/2007-04-11-InlineAsmVectorResult.ll

move a bunch of register constraints from being handled by

getRegClassForInlineAsmConstraint to being handled by
getRegForInlineAsmConstraint. This allows us to let the llvm register allocator
allocate, which gives us better code. For example, X86/2007-01-29-InlineAsm-ir.ll
used to compile to:
_run_init_process:
subl $4, %esp
movl %ebx, (%esp)
xorl %ebx, %ebx
movl $11, %eax
movl %ebx, %ecx
movl %ebx, %edx
# InlineAsm Start
push %ebx ; movl %ebx,%ebx ; int $0x80 ; pop %ebx
# InlineAsm End
Now we get:
_run_init_process:
xorl %ecx, %ecx
movl $11, %eax
movl %ecx, %edx
# InlineAsm Start
push %ebx ; movl %ecx,%ebx ; int $0x80 ; pop %ebx

rearchitect the registration mechanism used by the command line option stuff.
...
This dramatically reduce the amount of memory allocated by the commandline stuff
at static init time, changing it to build local data structures when ParseCommandLineOptions
is called. In a dummy empty program that links some llvm libraries, this reduces
the number of malloc'd bytes from 4864 to 3360 on entry to main. Most of that
memory is now allocated by non-commandline related stuff.
