Within the library, we never need to exponentiate modulo an even number.
In fact, all the remaining BN_mod_exp calls are modulo an odd prime.
This extends 617804adc5 to the rest of the

Noticed this comparing our and upstream's ASN.1 code. Somehow I missed
this line in cb852981cd. This change is a
no-op as our only ASN1_EX_COMBINE field is an ASN1_CHOICE which does not

asn1_template_noexp_d2i call ASN1_item_ex_free(&skfield,...) on error.
Reworked error handling in asn1_item_ex_combine_new:
- call ASN1_item_ex_free and return the correct error code if
ASN1_template_new failed.
- dont call ASN1_item_ex_free if ASN1_OP_NEW_PRE failed.
Reworked error handing in x509_name_ex_d2i and x509_name_encode.
(Imported from upstream's 748cb9a17f4f2b77aad816cf658cd4025dc847ee.)
I believe the tasn1_new.c change is a no-op since we have no
ASN1_OP_NEW_PRE hooks anymore. I'm not sure what the commit message is
referring to with ASN1_template_new. It also seems odd as
ASN1_item_ex_free should probably be able to survive *pval being NULL.
Whatever.
We'd previously tried to fix x509_name_ex_d2i, but I think ours wasn't
quite right. (This thing is a mess...) I've aligned that function with
upstream.

These were added in an attempt to deal with the empty vs. NULL confusion
in PKCS#12. Instead, PKCS8_encrypt and PKCS8_decrypt already treated
NULL special. Since we're stuck with supporting APIs like those anyway,
Chromium has been converted to use that feature. This cuts down on the
number of APIs we need to decouple from crypto/asn1.

In order to minimize dependency on assembler version a number of
post-SSE2 instructions are encoded manually. But in order to simplify
the procedure only register operands are considered. Non-register
operands are passed down to assembler. Module in question uses pshufb
with memory operands, and old [GNU] assembler can't handle it.
Fortunately in this case it's possible skip just the problematic
segment without skipping SSSE3 support altogether.

Original strategy for page-walking was adjust stack pointer and then
touch pages in order. This kind of asks for double-fault, because
if touch fails, then signal will be delivered to frame above adjusted
stack pointer. But touching pages prior adjusting stack pointer would
upset valgrind. As compromise let's adjust stack pointer in pages,
touching top of the stack. This still asks for double-fault, but at
least prevents corruption of neighbour stack if allocation is to
overstep the guard page.
Also omit predict-non-taken hints as they reportedly trigger illegal
instructions in some VM setups.

CFI directives annotate instructions that are significant for stack
unwinding procedure. In addition to directives recognized by GNU
assembler this module implements three synthetic ones:
- .cfi_push annotates push instructions in prologue and translates to
.cfi_adjust_cfa_offset (if needed) and .cfi_offset;
- .cfi_pop annotates pop instructions in epilogue and translates to
.cfi_adjust_cfs_offset (if needed) and .cfi_restore;
- .cfi_cfa_expression encodes DW_CFA_def_cfa_expression and passes it
to .cfi_escape as byte vector;
CFA expression syntax is made up mix of DWARF operator suffixes [subset
of] and references to registers with optional bias. Following example
describes offloaded original stack pointer at specific offset from
current stack pointer:
.cfi_cfa_expression %rsp+40,deref,+8
Final +8 has everything to do with the fact that CFA, Canonical Frame
Address, is reference to top of caller's stack, and on x86_64 call to
subroutine pushes 8-byte return address.

Precede the local labels with a non-local label to suppress these

It isn't clear why these labels are defined as local labels instead of
