92c4bb904f Fix the optimized code handling of user asm strings

5684598f3f Make BB and CPI labels use the function number, not the function name as a
uniquing id.  This makes things happy when the function name is quoted,
preventing labels like LBB"foo"_2.

91150e5d46 Allow per-character control over what target assemblers allow in symbol
names.  This also changes the default to allow all of "$_." in addition
to letters and numbers as symbol names.  If you don't want this, use
markCharUnacceptable to remove one of these or markCharAcceptable to add
to the set.  This corresponds with what GAS accepts by default.

Also, this includes some minor speedups

9ddf21276e Make this more efficient of the common case where we are only mangling globals.
Do not mangle internal global names that do not collide with anything.

This gives us strings that now look like this:

__2E_str_1:                             ; '.str_1'
        .asciz  "foo"

instead of this:

l1__2E_str_1:                           ; '.str_1'
        .asciz  "foo"

2980cefb80 add support for .asciz, and enable it by default. If your target assemblerdoesn't support .asciz, just set AscizDirective to null in your asmprinter.
This compiles C strings to:

l1__2E_str_1:                           ; '.str_1'
        .asciz  "foo"

instead of:

        .ascii  "foo\000"

a32551197a Change the ValueList array for each node to be shared instead of individuallyallocated. Further, in the common case where a node has a single value, justreference an element from a small array. This is a small compile-time win.

65113b2f86 Switch the operandlist/valuelist from being vectors to being just an array.This saves 12 bytes from SDNode, but doesn't speed things up substantially
(our graphs apparently already fit within the cache on my g5).  In any case
this reduces memory usage.
