For PR411:
...
This patch is an incremental step towards supporting a flat symbol table.
It de-overloads the intrinsic functions by providing type-specific intrinsics
and arranging for automatically upgrading from the old overloaded name to
the new non-overloaded name. Specifically:
llvm.isunordered -> llvm.isunordered.f32, llvm.isunordered.f64
llvm.sqrt -> llvm.sqrt.f32, llvm.sqrt.f64
llvm.ctpop -> llvm.ctpop.i8, llvm.ctpop.i16, llvm.ctpop.i32, llvm.ctpop.i64
llvm.ctlz -> llvm.ctlz.i8, llvm.ctlz.i16, llvm.ctlz.i32, llvm.ctlz.i64
llvm.cttz -> llvm.cttz.i8, llvm.cttz.i16, llvm.cttz.i32, llvm.cttz.i64
New code should not use the overloaded intrinsic names. Warnings will be
emitted if they are used.

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

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"

When moving constant entries in 'Map' if the entry is the representative

For large constants (e.g. arrays and structs with many elements) just

creating the keys and doing comparisons to index into 'Map' takes a lot
of time. For these large constants, keep an inverse map so that 'remove'

This speeds up a release build of the bc reader on Eric's nasty python
bytecode file from 1:39 to 1:00s.

constant arrays in place instead of reallocating them and replaceAllUsesOf'ing
the result. This speeds up a release build of the bcreader from:

to
49.790u 49.890s 1:40.14

Split SimpleConstantVal up into its components, so each Constant subclass getsa different enum value. This allows 'classof' for these to be really simple,not needing to call getType() anymore.
...
This speeds up isa/dyncast/etc for constants, and also makes them smaller.
For example, the text section of a release build of InstCombine.cpp shrinks
from 230037 bytes to 216363 bytes, a 6% reduction.
