Do not delete identity insert_subreg even if dest is virtual. Let later passes delete them. This avoids register scavenger complain.

VISIBILITY_HIDDEN removal.

Chris claims we should never have visibility_hidden inside any .cpp file but
that's still not true even after this commit.

This allows us to simplify this:
union vec2d {
    double e[2];
    double v __attribute__((vector_size(16)));
};
typedef union vec2d vec2d;

static vec2d a={{1,2}}, b={{3,4}};
    
vec2d foo () {
    return (vec2d){ .v = a.v + b.v * (vec2d){{5,5}}.v };
}

down to:

define %0 @foo() nounwind ssp {
entry:
  %mrv5 = insertvalue %0 undef, double 1.600000e+01, 0 ; <%0> [#uses=1]
  %mrv6 = insertvalue %0 %mrv5, double 2.200000e+01, 1 ; <%0> [#uses=1]
  ret %0 %mrv6
}

instead of:

define %0 @foo() nounwind ssp {

  %mrv5 = insertvalue %0 undef, double extractelement (<2 x double> fadd (<2 x double> fmul (<2 x double> bitcast (<1 x i128> <i128 85174437667405312423031577302488055808> to <2 x double>), <2 x double> <double 3.000000e+00, double 4.000000e+00>), <2 x double> <double 1.000000e+00, double 2.000000e+00>), i32 0), 0 ; <%0> [#uses=1]

When functions are compiled, they accumulate references in the JITResolver's
stub maps. This patch removes those references when the functions are
destroyed.  It's illegal to destroy a Function when any thread may still try to
call its machine code.

This patch also updates r83987 to use ValueMap instead of explicit CallbackVHs
and fixes a couple "do stuff inside assert()" bugs from r84522.
