[Modules] Allow @import to reach submodules in private module maps
A @import targeting a top level module from a private module map file
(@import Foo_Private), would fail if there's any submodule declaration
around (module Foo.SomeSub) in the same private module map.
This happens because compileModuleImpl, when building Foo_Private, will
start with the private module map and will not parse the public one,
which leads to unsuccessful parsing of Foo.SomeSub, since top level Foo
was never parsed.
Declaring other submodules in the private module map is not common and
should usually be avoided, but it shouldn't fail to build. Canonicalize
compileModuleImpl to always look at the public module first, so that all
necessary information is available when parsing the private one.

If you include both headers and use some single-inclusion mechanism

So that we get an accurate dependency file, we therefore need to also

Teach AsmParser to check with Assembler for when evaluating constant
expressions. This improves the handing of preprocessor expressions
that must be resolved at parse time. This idiom can be found as
assembling-time assertion checks in source-level assemblers. Note that
this relies on the MCStreamer to keep sufficient tabs on Section /
Fragment information which the MCAsmStreamer does not. As a result the
textual output may fail where the equivalent object generation would
pass. This can most easily be resolved by folding the MCAsmStreamer
and MCObjectStreamer together which is planned for in a separate
patch.
Currently, this feature is only enabled for assembly input, keeping IR
compilation consistent between assembly and object generation.

[Targets] Implement getConstraintRegister for ARM and AArch64
Summary:
The getConstraintRegister method is used by semantic checking of
inline assembly statements in order to diagnose conflicts between
clobber list and input/output lists. Currently ARM and AArch64 don't
override getConstraintRegister, so conflicts between registers
assigned to variables in asm labels and clobber lists are not
diagnosed. Such conflicts can cause assertion failures in the back end
and even miscompilations.
This patch implements getConstraintRegister for ARM and AArch64
targets. Since these targets don't have single-register constraints,
the implementation is trivial and just returns the register specified
in an asm label (if any).

PR37189 Fix incorrect end source location and spelling for a split '>>' token.
When a '>>' token is split into two '>' tokens (in C++11 onwards), or (as an
extension) when we do the same for other tokens starting with a '>', we can't
just use a location pointing to the first '>' as the location of the split
token, because that would result in our miscomputing the length and spelling
for the token. As a consequence, for example, a refactoring replacing 'A<X>'
with something else would sometimes replace one character too many, and
similarly diagnostics highlighting a template-id source range would highlight
one character too many.
Fix this by creating an expansion range covering the first character of the
'>>' token, whose spelling is '>'. For this to work, we generalize the
expansion range of a macro FileID to be either a token range (the common case)
or a character range (used in this new case).

[RISCV] More validations on the input value of -march=
Supporting additional rules for parsing ISA string.
- RISC-V ISA strings must be lowercase.
E.g.: rv32IMC is not supported, rv32imc is correct.
- Multi-letter extensions are to be separated by a single
underscore '_'. The extension prefix counts as a letter.
This means extensions that start with 's', 'sx' and 'sx'
are all multi-letter.
E.g.:
xasb is a single non-standard extension named 'xasb'
xa_sb are two extensions, the non-standard user level extension
'xa', and the supervisor level extension 'sb'.
- Standard user-level extensions are specified following
a canonical order, according to Table 22.1 in
RISC-V User-Level ISA V2.2.
- Non-standard user-level 'x' extensions,
standard supervisor-level 's' extensions and
non-standard supervisor-level 'sx' extensions
are also specified following a canonical order according
to Table 22.1 in RISC-V User-Level ISA V2.2:
'x' extensions, follwed by 's' extensions and then 'sx' extensions.
- Extensions might have a version number.
Underscores may be used to separate ISA subset components to
improve readability and to provide disambiguation.
E.g.: rv32i2_m3_a1_f2_d2
- Version numbers are divided into major and minor numbers,
separated by a 'p'. If the minor version is 0, then 'p0' can
be omitted.
- Additional checks for dependent extensions and invalid
extensions combinations.
E.g.:
'e' requires rv32
'e' can't be combined with 'f' nor 'd'
'q' requires rv64
- TODO items have also been marked with comments in the code.

[analyzer] Enable analysis of WebKit "unified sources".
Normally the analyzer begins path-sensitive analysis from functions within
the main file, even though the path is allowed to go through any functions
within the translation unit.
When a recent version of WebKit is compiled, the "unified sources" technique
is used, that assumes #including multiple code files into a single main file.
Such file would have no functions defined in it, so the analyzer wouldn't be
able to find any entry points for path-sensitive analysis.
This patch pattern-matches unified file names that are similar to those
used by WebKit and allows the analyzer to find entry points in the included
code files. A more aggressive/generic approach is being planned as well.
